info

To learn more about security at Camunda, including our security policy, security issue management, and more, see Camunda.com/security.

Understand affected and fixed versions​

Each security notice lists affected and fixed versions by Camunda component (for example, Zeebe, Operate, Tasklist, Identity, Optimize, and Hub), not by Helm chart version. The Helm chart has its own version, tracked separately from the component versions it deploys.

For Camunda 8.8 and later, the Orchestration Cluster unifies Zeebe, Operate, and Tasklist, so these components share the same version number.

To check whether your Helm deployment is affected:

  1. Identify the Helm chart version you are running.
  2. In the Helm chart version matrix, find the component versions that the chart deploys.
  3. Compare those component versions with the affected and fixed versions listed in the notice.

Products affected​

  • Camunda Orchestration Cluster (Zeebe, Operate, Tasklist)
  • Camunda Zeebe, Operate, and Tasklist (8.7)
  • Camunda Zeebe (8.6)
  • Camunda Optimize
  • Camunda Management Identity (Identity in 8.6)
  • Camunda Connectors
  • Hub Self-Managed 8.10
  • Web Modeler Self-Managed 8.6, 8.7, 8.8, and 8.9
  • Console Self-Managed 8.7, 8.8, and 8.9
  • Camunda Keycloak images (camunda/keycloak and registry.camunda.cloud/keycloak-ee/keycloak)

Impact​

The certificate authority eMudhra reported that an attacker compromised some of its intermediate certificate authorities. Oracle published two Java security alerts for this compromise:

  • CVE-2026-91403 removes the root certificates "emSign ECC Root CA - G3" and "AAA Certificate Services" from the Java trust store.
  • CVE-2026-114820 also removes "emSign Root CA - G1" and "emSign Root CA - G2".

Severity: Critical (CVSS 9.1, CVE-2026-114820).

The trust stores in the affected images contain some of these root certificates.

Exploitation requires an attacker who also controls the network path, for example through DNS poisoning or a compromised network device. The attacker can then do a man-in-the-middle attack on outgoing TLS connections from Camunda components, with a certificate that a compromised intermediate signed.

We have no evidence that an attacker used this against Camunda. This issue does not affect Camunda keys and secrets. No public Camunda endpoint uses an eMudhra certificate. If you suspect a man-in-the-middle attack on an outgoing connection, rotate the credentials that this connection sends.

How to determine if the installation is affected​

You are using:

  • Camunda Orchestration Cluster ≤ 8.10.5, ≤ 8.9.25, or ≤ 8.8.43
  • Camunda Zeebe, Operate, or Tasklist ≤ 8.7.43
  • Camunda Zeebe ≤ 8.6.40
  • Camunda Optimize ≤ 8.10.5, ≤ 8.9.25, ≤ 8.8.43, or ≤ 8.7.29
  • Camunda Connectors ≤ 8.10.1, ≤ 8.9.16, ≤ 8.8.23, ≤ 8.7.29, or ≤ 8.6.33
  • Camunda Management Identity ≤ 8.10.1, ≤ 8.9.11, ≤ 8.8.19, or ≤ 8.7.26
  • Camunda Identity ≤ 8.6.33
  • Hub Self-Managed ≤ 8.10.4
  • Web Modeler Self-Managed ≤ 8.9.13 or ≤ 8.8.24, or any 8.6 or 8.7 version
  • Console Self-Managed ≤ 8.9.129, ≤ 8.8.146, or ≤ 8.7.114
  • A Camunda Keycloak image built before October 22, 2026, or a Camunda Keycloak image for Keycloak 23, 24, or 25

To see when an image was built, run docker inspect -f '{{.Created}}' <image>.

Solution​

Camunda has provided the following releases which contain the fix for CVE-2026-91403 ("emSign ECC Root CA - G3" and "AAA Certificate Services" are removed from the trust stores):

  • Camunda Orchestration Cluster 8.10.6, 8.9.26, 8.8.44
  • Camunda Zeebe, Operate, and Tasklist 8.7.44
  • Camunda Zeebe 8.6.41
  • Camunda Optimize 8.10.6, 8.9.26, 8.8.44, 8.7.30
  • Camunda Connectors 8.10.2, 8.9.17, 8.8.24, 8.7.30, 8.6.34
  • Camunda Management Identity 8.10.2, 8.9.12, 8.8.20, 8.7.27
  • Hub Self-Managed 8.10.5
  • Web Modeler Self-Managed 8.9.14, 8.8.25
  • Camunda Identity 8.6.34
  • Console Self-Managed 8.9.130, 8.8.147, 8.7.115
  • Camunda Keycloak images built on or after October 22, 2026:
    • camunda/keycloak with the 26.3.3 tag. This is the default image of the bundled identityKeycloak subchart in Camunda 8.7 to 8.9. This tag receives no more updates. For details, see Keycloak support, security fixes, and upgrades.
    • camunda/keycloak with the quay-26.8.1, quay-optimized-26.8.1, or latest tag
    • registry.camunda.cloud/keycloak-ee/keycloak with the 26.8.1 tag, which values-enterprise.yaml uses in Camunda 8.7 to 8.9

If you use one of these Keycloak tags, pull the image again and restart Keycloak. With imagePullPolicy: IfNotPresent or a mirrored registry, the old image can stay in use. Update your mirror and make sure that the new image runs.

The base images for Keycloak 23, 24, and 25 receive no more updates, so these Camunda Keycloak images do not get the fix. If you use Keycloak 23, 24, or 25, upgrade to a fixed Keycloak 26 image. Refer to Prepare a Keycloak upgrade.

The releases above still trust "emSign Root CA - G1", which CVE-2026-114820 also removes. Eclipse Temurin and Mozilla keep this root because it is not related to the compromised intermediates. To follow CVE-2026-114820, remove it with the workaround below. We will update this notice when we release images without it.

A fix for Web Modeler Self-Managed 8.6 and 8.7 is not available yet. Their REST API images still trust the root certificates. Use the workaround below. We will update this notice when we release the fix. Camunda Operate, Tasklist, and Optimize 8.6 are not affected. Their images use a trust store that does not contain the root certificates.

If you can't upgrade immediately, remove the four root certificates from the Java truststore of the Camunda Java components that the Helm chart deploys. For step-by-step instructions, see Remove a CA from the JVM truststore. This procedure does not cover Keycloak or Console. For Camunda 8.6 and 8.7, contact Camunda Support for the workaround procedure.

On Camunda 8 SaaS, if you disabled the automatic upgrade of your clusters, we recommend that you update them to the latest available patch version.

Notice 79​

Publication date​

November 2, 2026

Products affected​

  • Zeebe
  • Operate
  • Tasklist
  • Optimize

Impact​

CVE-2026-71290 is a TLS hostname verification bypass in the asynchronous client of Apache HttpClient 5 (httpclient5 5.4 through 5.6.3). Camunda uses this client to connect to Elasticsearch and OpenSearch. An attacker in a network position to intercept traffic (for example, through DNS spoofing or a compromised host on a shared network segment) can impersonate the search backend with a valid certificate for another domain. This can expose Basic authentication credentials sent to the backend, expose or modify process data in transit, and allow forged responses.

This notice covers the 8.6 line. For the 8.7 fixes, see Notice 60.

How to determine if the installation is affected​

You are using one of the following components, and it connects to Elasticsearch or OpenSearch over TLS:

  • Zeebe, Operate, or Tasklist ≤ 8.6.39
  • Optimize ≤ 8.6.27

Solution​

Camunda has provided the following releases which contain the fix:

  • Zeebe, Operate, Tasklist: 8.6.40
  • Optimize: 8.6.28

Notice 78​

Publication date​

November 2, 2026

Products affected​

Identity

Impact​

CVE-2026-68763 is an uncontrolled resource consumption flaw in Apache Tomcat. A memory leak occurs in the HTTP/2 handling when a client resets a stream.

Identity enables HTTP/2 by default, so an attacker who can reach its HTTP port can exhaust memory and cause a denial of service without authenticating. The flaw does not allow reading or changing data. Because Identity is central to multi-tenancy, an outage can disrupt the wider automation stack.

How to determine if the installation is affected​

You are using Identity before 8.6.34, with the default server.http2.enabled: true, and the Identity port is reachable by untrusted clients.

Solution​

Camunda has provided the following releases which contain the fix:

  • Identity: 8.6.34 (included in the Camunda 8.6.41 Docker image)

As a workaround, set server.http2.enabled to false.

Notice 77​

Publication date​

November 2, 2026

Products affected​

Operate, Tasklist

Impact​

CVE-2026-41720 is a flaw in Spring LDAP: bind requests with a non-empty username and an empty or null password are not rejected. In Operate or Tasklist with legacy LDAP authentication enabled (ldap-auth profile), an attacker who knows a valid username may authenticate with a blank password and gain access to the web application, if the LDAP directory accepts such binds. Other deployments are not affected.

How to determine if the installation is affected​

You are using Operate or Tasklist with the ldap-auth profile enabled, before 8.6.40.

Solution​

Camunda has provided the following releases which contain the fix:

  • Operate, Tasklist: 8.6.40

As a workaround, configure your LDAP server to reject unauthenticated (empty-password) binds.

Notice 76​

Publication date​

November 2, 2026

Products affected​

Zeebe, Operate, Tasklist, Identity, and Optimize

Impact​

CVE-2026-40984 is a denial of service in Micrometer's HTTP request instrumentation. Spring Boot applies it automatically to all HTTP endpoints. An unauthenticated attacker who can reach any HTTP endpoint can send a specially crafted request that drives the instrumentation into excessive resource use, making the component unresponsive until restart. This affects availability only; it does not expose or modify data.

How to determine if the installation is affected​

You are using one of the following components with HTTP endpoints reachable by untrusted clients:

  • Zeebe, Operate, Tasklist before 8.6.40
  • Identity before 8.6.31
  • Optimize before 8.6.27

Solution​

Camunda has provided the following releases which contain the fix:

  • Zeebe, Operate, Tasklist: 8.6.40
  • Identity: 8.6.31
  • Optimize: 8.6.27

Notice 75​

Publication date​

November 2, 2026

Products affected​

Zeebe

Impact​

CVE-2026-40983 is a denial of service in Micrometer's gRPC server instrumentation. The Zeebe Gateway applies this interceptor to its public gRPC API with no way to disable it. An unauthenticated attacker with network access can send crafted gRPC requests and exhaust resources, making the gateway unresponsive until it is restarted. All client operations (job polling, deployments, message publication, and process instance creation) are interrupted. Operate, Tasklist, and Identity include the library but do not run a gRPC server, so they are not exploitable.

How to determine if the installation is affected​

You are using Zeebe before 8.6.40, with the gateway endpoint reachable by untrusted clients.

Solution​

Camunda has provided the following releases which contain the fix:

  • Zeebe: 8.6.40

Notice 74​

Publication date​

November 2, 2026

Products affected​

Zeebe

Impact​

CVE-2026-42587 is a decompression limit bypass in Netty. The maxAllocation limit is not enforced when the content encoding is Brotli, zstd, or Snappy. An unauthenticated attacker can send a small compressed payload that causes unbounded memory allocation. This leads to an out-of-memory denial of service on the Zeebe Gateway, whose Netty HTTP/2 endpoint is reachable from outside the cluster. Other components have a much lower likelihood. Data is not disclosed or modified.

How to determine if the installation is affected​

You are using Zeebe before 8.6.40, with the gateway endpoint reachable by untrusted clients.

Solution​

Camunda has provided the following releases which contain the fix:

  • Zeebe: 8.6.40

Notice 73​

Publication date​

November 2, 2026

Products affected​

Zeebe, Operate, Tasklist, Identity, and Optimize

Impact​

CVE-2026-42585 is an HTTP request smuggling flaw in Netty. It comes from incorrect parsing of malformed Transfer-Encoding headers. If an affected component sits behind a reverse proxy, load balancer, or Ingress that parses the request boundary differently, an attacker can smuggle a second request past front-end checks such as authentication or WAF rules. Depending on the setup, this can lead to unauthorized access to protected endpoints, cache poisoning, or session abuse. HTTPS does not prevent it.

How to determine if the installation is affected​

You are using the following components behind a reverse proxy, load balancer, or Ingress:

  • Zeebe, Operate, Tasklist before 8.6.40
  • Identity before 8.6.31
  • Optimize before 8.6.27

Solution​

Camunda has provided the following releases which contain the fix:

  • Zeebe, Operate, Tasklist: 8.6.40
  • Identity: 8.6.31
  • Optimize: 8.6.27

Notice 72​

Publication date​

November 2, 2026

Products affected​

Operate, Tasklist, and Zeebe Java Client (io.camunda:zeebe-client-java)

Impact​

CVE-2026-68494 is an incomplete fix for a number-length limit bypass in the non-blocking parser of jackson-core. The Zeebe Java Client (io.camunda:zeebe-client-java) uses that parser to read chunked API responses. Operate and Tasklist use the Zeebe Java Client and can be affected transitively. A malicious or compromised response could make the client process hang or run out of memory.

How to determine if the installation is affected​

You are using:

  • Operate or Tasklist before 8.6.40, because these components use the affected Zeebe Java Client dependency
  • Zeebe Java Client (io.camunda:zeebe-client-java) before 8.6.40 with a jackson-core version in the affected range, connecting to an endpoint you do not fully trust

Solution​

Camunda has provided the following releases which contain the fix:

  • Operate, Tasklist, and Zeebe Java Client (io.camunda:zeebe-client-java): 8.6.40

Notice 71​

Publication date​

November 2, 2026

Products affected​

Zeebe, Operate, Tasklist, Identity, and Optimize

Impact​

CVE-2026-34282 is a flaw in the networking component of the Oracle JDK shipped in Camunda container images (OpenJDK 21.0.10). A TLS peer can cause a blocking network call to hang indefinitely, which pins the handling thread. Enough requests can exhaust the web server's thread pool and make the component unresponsive to all users (denial of service).

Exploitation has strong preconditions. The component must run with OpenID Connect (OIDC) authentication against an identity provider reached over HTTPS, and the attacker must control or sit on the path to that identity provider. Confidentiality and integrity are not affected.

How to determine if the installation is affected​

You are using:

  • Zeebe, Operate, Tasklist before 8.6.40
  • Identity before 8.6.31
  • Optimize before 8.6.27

Solution​

Camunda has provided the following releases which contain the fix:

  • Zeebe, Operate, Tasklist: 8.6.40
  • Identity: 8.6.31
  • Optimize: 8.6.27

Notice 70​

Publication date​

October 26, 2026

Products affected​

  • Camunda Web Modeler

Impact​

Web Modeler Self-Managed is affected by CVE-2026-111497, a critical-severity out-of-bounds write in the Node.js Brotli decoder that can allow remote code execution.

The Web Modeler Self-Managed 8.7 and 8.8 webapp images contain a Node.js runtime. An authenticated Web Modeler user can reach the affected decoder through the "import resources from URL" capability: the webapp server fetches URLs that the user supplies and automatically decodes Brotli-compressed responses. A server controlled by an attacker can return a crafted Brotli response that triggers the out-of-bounds write in the Node.js process.

How to determine if the installation is affected​

You are using:

  • Web Modeler Self-Managed ≤ 8.7.27, or ≤ 8.8.23

Solution​

Camunda has provided the following releases which contain the fix (Node.js 24.22.1):

  • Web Modeler Self-Managed 8.7.28, 8.8.24

No action is necessary for Camunda SaaS.

Notice 69​

Publication date​

October 26, 2026

Products affected​

  • Hub Self-Managed 8.10
  • Web Modeler Self-Managed 8.7, 8.8, and 8.9

Impact​

Two critical vulnerabilities in PHP (CVE-2026-109618 and CVE-2026-109619) were disclosed on 20 October 2026. Our security and engineering teams have analyzed both in detail. We found no way to exploit them in any Camunda product. Out of an abundance of caution, we have released updated images with the fixed PHP version.

Which products are concerned​

  • SaaS: Camunda SaaS does not use PHP and is not affected.
  • Self-Managed: The websockets component of Hub (version ≤ 8.10.3) and Web Modeler (versions ≤ 8.9.12, ≤ 8.8.23, or ≤ 8.7.27) runs PHP 8.5.11, a version in the affected range.
  • No other Camunda 8 component uses PHP.

Why the vulnerabilities cannot be exploited​

Both vulnerabilities are in the way PHP processes incoming web requests when it runs inside a web server (for example PHP-FPM or Apache with mod_php). The websockets component does not run PHP that way. It runs as a standalone process that reads and validates requests itself, never uses PHP's request handling, and accepts only small, size-limited messages. None of the attack paths described in the CVE advisories can reach it.

What you need to do​

No immediate action is required. We recommend updating to the new images as part of your normal update process.

If your own policy requires it, you can stop the websockets component until you have updated. Web Modeler and Hub keep working, and all modeling, saving, deployment, versioning and Git sync functionality is unaffected. Only features that rely on real-time updates are affected while the component is stopped.

  • Real-time collaboration: online presence, live diagram updates, live comments, attention markers and live changes to project permissions are not delivered. Collaborators see each other's changes only after reloading the page, concurrent changes might conflict / overwrite each other.
  • AI copilot (8.8 and later): copilot responses are delivered through the websockets component and are not returned while it is stopped.
  • Intelligent Document Processing (8.8 and later): extraction results are delivered through the websockets component and are not shown in the modeler while it is stopped.

How to determine if the installation is affected​

You are using:

  • Hub ≤ 8.10.3
  • Web Modeler ≤ 8.9.12, ≤ 8.8.23, or ≤ 8.7.27

Solution​

Camunda has provided the following releases which contain the fix (update to PHP 8.5.12):

  • Hub 8.10.4
  • Web Modeler 8.9.13, 8.8.24, 8.7.28

Notice 68​

Publication date​

October 20, 2026

Products affected​

  • Management Identity Self-Managed 8.8, 8.9, and 8.10
  • Orchestration Cluster 8.9 and 8.10, when PostgreSQL is used as secondary storage (RDBMS)
  • Web Modeler Self-Managed 8.8 and 8.9, when PostgreSQL is used as RDBMS
  • Hub Self-Managed 8.10, when PostgreSQL is used as RDBMS

Impact​

The PostgreSQL JDBC driver (org.postgresql:postgresql) versions 42.7.11 to 42.7.13 used by Camunda are affected by CVE-2026-107314. If the requireAuth connection property excludes every authentication method, or lists no method at all, the driver doesn't restrict the authentication method. A man-in-the-middle attacker between Camunda and PostgreSQL can then request cleartext password authentication and obtain the database password.

The following values trigger the issue:

  • requireAuth=!password,!md5,!gss,!sspi,!scram-sha-256,!none (excludes every method)
  • requireAuth=, (lists no method)

Severity: High. The upstream CVSS 3.1 base score for the library is 5.9 (AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:N).

The requireAuth property has no default value, and Camunda doesn't set it. Only installations that set the property as described are affected.

How to determine if the installation is affected​

Your installation is affected if all of these conditions are true:

  • You run one of the following Camunda products on a version earlier than the fixed versions listed in the solution:
    • Management Identity 8.8 to 8.10
    • Orchestration Cluster 8.9 or 8.10 with PostgreSQL as secondary storage
    • Web Modeler 8.8 or 8.9 with PostgreSQL
    • Hub 8.10 with PostgreSQL
  • The JDBC URL or datasource properties for the PostgreSQL connection set requireAuth to a value that excludes all authentication methods, or that contains no method.
  • The database connection doesn't use TLS with full server verification (sslmode=verify-full).

Solution​

Camunda has provided the following releases which contain the fix (driver version 42.7.14):

  • Orchestration Cluster: 8.10.4, 8.9.24
  • Management Identity: 8.10.1, 8.9.11, 8.8.19
  • Web Modeler: 8.9.11, 8.8.22
  • Hub: 8.10.3

If your configuration sets requireAuth to one of the affected values, replace it with a positive list of the authentication methods your PostgreSQL server uses, for example requireAuth=scram-sha-256, before you upgrade. After the upgrade, the driver refuses connections that use a value excluding every method (SQLState 08004), and rejects a value that lists no method as invalid (SQLState 22023).

If you can't upgrade immediately, use one of these workarounds:

  • Replace the requireAuth value with a positive list of allowed methods on your current version, as described above.
  • Connect to PostgreSQL with sslmode=verify-full.

  • Camunda Helm chart for Camunda 8.7, 8.8, and 8.9, when the bundled Keycloak subchart (identityKeycloak) uses the default Community Edition image

Impact​

Keycloak is affected by CVE-2026-18963, a flaw in the reset-credentials flow. An unauthenticated attacker can force a password reset for any user without the email verification step, set new credentials, and take over the account, including administrator accounts.

Severity: Critical (CVSS 9.1).

The bundled Keycloak subchart in the Camunda 8.7, 8.8, and 8.9 Helm charts defaults to the Community Edition image camunda/keycloak:26.3.3. This image is based on the Bitnami Keycloak image, which Bitnami no longer updates. As a result, Camunda cannot publish a fixed image on this line, and the image will not receive this or any future fix.

Camunda SaaS is not affected.

How to determine if the installation is affected​

The following Keycloak versions are affected:

  • ≥ 26.0.0, < 26.4.15
  • ≥ 26.5.0, < 26.6.6
  • ≥ 26.7.0, < 26.7.2

Your installation is affected if all of these conditions are true:

  • You deploy Camunda 8.7, 8.8, or 8.9 with the Camunda Helm chart, and the bundled Keycloak subchart is enabled (identityKeycloak.enabled: true).
  • You use the default camunda/keycloak image (tag 26.3.3, any 26.3.3-* rebuild tag, or the bitnami-* and latest-bitnami tags), or another Keycloak image with an affected version.

Camunda Helm chart 12.13.6 (Camunda 8.7), 13.13.2 (Camunda 8.8), 14.10.1 (Camunda 8.9), and later show a security warning when the rendered Keycloak image is affected.

If you run Keycloak outside the Camunda Helm chart, your installation is affected if your Keycloak version is in one of the affected ranges.

The Camunda 8.10 Helm chart does not include a bundled Keycloak subchart and is not affected. If you use your own Keycloak with Camunda 8.10, check your Keycloak version as described above.

Solution​

The following Keycloak versions contain the fix:

  • 26.4.15
  • 26.6.6
  • 26.7.2

Camunda does not provide a fixed Community Edition image for the bundled Keycloak subchart. Use one of these options:

  • Use the Camunda enterprise images: Enterprise customers can switch to the Bitnami Premium images provided by Camunda. The enterprise Keycloak image registry.camunda.cloud/keycloak-ee/keycloak receives security updates and contains the fix from version 26.7.2. Camunda Helm chart 12.13.4 (Camunda 8.7), 13.12.8 (Camunda 8.8), 14.8.5 (Camunda 8.9), and later use a fixed Keycloak version in values-enterprise.yaml.
  • Migrate away from the bundled Keycloak subchart: Replace the bundled Keycloak with the Keycloak Operator, a managed service, or another maintained Keycloak deployment that runs a fixed version. For step-by-step instructions, see migrate from Bitnami subcharts.

After you apply the fix, examine Keycloak events and user accounts for password resets that you do not expect, and reset the credentials of any affected accounts.

No action is necessary for Camunda SaaS.

  • Camunda Optimize Self-Managed

Impact​

The Docker images camunda/optimize:8.10.0 and camunda/optimize:8.10.1 were available for a short time before the Camunda 8.10 release announcement. These images contain a defect in the Optimize access check. In Self-Managed installations that use Management Identity, users without the Optimize permission can get access to Optimize. This includes read access to Optimize data, and changes to Optimize entities such as reports and dashboards.

Exploitation requires a user who can log in to the identity provider that Optimize uses. Unauthenticated access is not possible.

We removed the affected images from Docker Hub. No official Camunda Helm chart release referenced these images. Camunda SaaS is not affected.

How to determine if the installation is affected​

Your installation is affected if all of these conditions are true:

  • You run Camunda Optimize Self-Managed with the image camunda/optimize:8.10.0 or camunda/optimize:8.10.1. This includes images with these tags that you copied to your own registry. If you install with an official Camunda Helm chart release and do not override the Optimize image, you do not use these images.
  • Optimize uses Management Identity for authentication.

Optimize 8.9 and earlier versions are not affected.

Solution​

Upgrade Optimize to version 8.10.2 immediately. Optimize 8.10.2 contains the fix.

If you used the image camunda/optimize:8.10.0 or camunda/optimize:8.10.1:

  1. Upgrade to camunda/optimize:8.10.2.
  2. Remove the affected images from your private registries and image caches.
  3. Examine the Optimize data, for example reports, dashboards and collections, for changes that you do not expect.

No action is necessary for Camunda SaaS.

Products affected​

  • Camunda Orchestration Cluster (Zeebe, Operate, Tasklist)
  • Camunda Zeebe (8.7)

Impact​

The document endpoint of the Orchestration Cluster REST API rendered uploaded document content in the browser instead of downloading it. A user allowed to upload documents could use this to run scripts in the application's origin with the privileges of another user who opens the document, including administrators.

Severity: High.

How to determine if the installation is affected​

You are using:

  • Camunda Orchestration Cluster ≤ 8.9.22 or ≤ 8.8.40
  • Camunda Zeebe ≤ 8.7.42

Solution​

Camunda has provided the following releases which contain the fix:

  • Camunda Orchestration Cluster 8.10.0, 8.9.23, 8.8.41
  • Camunda Zeebe 8.7.43

Products affected​

  • Camunda Orchestration Cluster (Zeebe, Operate, Tasklist)
  • Camunda Connectors
  • Camunda Web Modeler

Impact​

A remote code execution vulnerability was identified in Camunda's FEEL expression engine allowing execution of arbitrary code within the scope of a Camunda 8 server operating system process.

Severity: Critical 9.9 (CVSS v3.1: AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H).

This vulnerability was identified by Camunda's Security Team, with no known report or exploit beyond our own security investigation. A CVE identifier has been requested and this notice will be updated once it is assigned. For further details, see GHSA-vx3p-v6cf-vfjw.

How to determine if the installation is affected​

You are using:

  • Camunda Orchestration Cluster ≤ 8.9.19 or ≤ 8.8.37
  • Camunda Zeebe, Operate, or Tasklist ≤ 8.7.39
  • Camunda Connectors ≤ 8.9.10, ≤ 8.8.19, or ≤ 8.7.25
  • Web Modeler ≤ 8.9.8, or ≤ 8.8.19

Any component that bundles org.camunda.feel:feel-engine up to and including 1.22.0 is affected. Versions older than the ones listed above, including versions that have reached end of maintenance, are also affected, with the exception of Web Modeler, where versions below 8.8.0 are not affected.

Exploitation requires one of the following:

  • The attacker is an authenticated and authorized user of the Camunda Orchestration Cluster REST API 8.9+ who has the privilege to invoke the Evaluate Expression API. The authorization requires:
    • Permission granted to user or client (directly or via role)
    • Resource type: EXPRESSION
    • Permission: EVALUATE
    • By default, this permission is granted as part of the admin role
  • The attacker is an authenticated and authorized user who has the privilege to deploy BPMN or DMN to the Camunda Orchestration Cluster:
    • Prior to 8.8: API access (gRPC or REST)
    • Starting 8.8: via gRPC or REST
    • The authorization requires:
      • Permission granted to user or client (directly or via role)
      • Resource type: Resource
      • Permission: CREATE
      • By default, this permission is granted as part of the admin role
  • The attacker is an authenticated and authorized user of Camunda Web Modeler ≤ 8.9.8 or ≤ 8.8.19

Solution​

Camunda has provided the following releases which contain the fix:

  • Camunda Orchestration Cluster 8.9.21, 8.8.39
  • Camunda Zeebe, Operate, Tasklist 8.7.41
  • Camunda Connectors 8.9.12, 8.8.21, 8.7.27
  • Web Modeler Self-Managed 8.9.9, 8.8.20

These releases bundle a patched FEEL engine (1.22.1, 1.21.1, 1.20.3, 1.19.6, 1.18.6, 1.17.13, 1.16.6, or 1.15.5, depending on the component). If you embed the FEEL engine directly, upgrade org.camunda.feel:feel-engine to the patched version of your 1.x line.

Camunda 8 SaaS was fully remediated on September 12 and 13, 2026, ahead of this notice. All clusters across all supported versions, and Web Modeler SaaS, were updated to patched builds; no action is required on your part. Clusters that were suspended at that time receive the patched version when they resume.

Products affected​

  • Camunda Optimize

Impact​

The application was vulnerable to the following vulnerabilities in the embedded Eclipse Jetty web server:

  • CVE-2026-19203, where a flaw in HTTP/1.1 chunked request parsing accepts a lone line feed (LF) character as a terminator in parts of chunked requests. When deployed behind an intermediary reverse proxy that requires strict CRLF delimiters, this discrepancy in request boundary interpretation can lead to HTTP request smuggling.
  • CVE-2026-12611, where a race condition in the HTTP/2 server implementation when handling concurrent RST_STREAM and GOAWAY frames from a client can cause write-blocked threads to never be unblocked, potentially leading to thread exhaustion and a Denial of Service. The default Camunda Optimize configuration is not exploitable; this vulnerability only applies when HTTP/2 support is explicitly enabled (container.http2Enabled: true).

Notice 61​

Publication date​

September 8, 2026

Products affected​

  • Camunda Connectors

Impact​

The connector runtime resolves a secret reference (for example, {{secrets.MY_API_KEY}}) wherever that literal text appears in a connector's input, without restricting resolution to the field where the reference was declared. Under the following conditions, an attacker may be able to cause a connector to resolve and disclose a secret outside its intended scope:

  • The process uses connectors and secrets.
  • Untrusted input reaches a process variable — for example, through a user task, an inbound connector such as a webhook or email, or an API call.
  • That process variable is passed, unsanitized, into a connector field (for example, an email body or an HTTP request field).
  • The attacker can guess or know the name of a secret that exists in that context. This does not require knowing the secret's value, only its name.
  • The connector's destination is one the attacker controls or can observe, or the attacker can also influence the destination itself (for example, a recipient address or URL supplied through another process variable).

Severity: High (CVSS 7.5).

How to determine if the installation is affected​

You are using:

  • Camunda Connectors 8.1.x through 8.9.x, on Self-Managed or SaaS, with connectors and secrets configured as described above.

Solution​

Camunda has released a secret filter for the connector runtime, defaulting to STRICT mode. In STRICT mode, a connector only resolves a secret that's present for that specific field in the deployed BPMN XML, which structurally closes this vulnerability for both outbound and inbound connectors. This is a breaking change: after upgrading, a connector field that relied on resolving an undeclared secret stops resolving it. See secret filter for configuration details, including how to change the mode.

Camunda has provided the following releases which contain the fix:

  • Camunda Connectors 8.9.10, 8.8.19, 8.7.25, 8.6.28

On Camunda 8 SaaS, this fix is included automatically unless you've opted out of auto-updates, in which case you'll need to update your cluster manually. You can also change the mode per cluster in cluster settings.

Interim mitigation:

  • Review your process deployments against the preconditions above.
  • If a process may be affected, search its process instance variables for a secret-reference literal — for example, using the Search process instances API with a $like filter on 8.8 and later. This check is not conclusive: it only reflects the variable's current value, within your retention period.
  • Adjust the affected process so the preconditions above no longer hold, or sanitize the process variable to remove secret-reference syntax before it reaches a connector field.
    • Sanitize the respective process variable for example by replacing secrets keyword: = replace(emailBody, "secrets?\.", "secretx_", "i")
  • Rotate any secret that may have been exposed, following your organization's secret-management procedures.

Products affected​

  • Camunda Zeebe
  • Camunda Tasklist
  • Camunda Operate
  • Camunda Optimize

Impact​

The application was vulnerable to CVE-2026-71290, where the embedded httpclient5 library's asynchronous transport, used to connect to the Elasticsearch/OpenSearch secondary storage, skipped hostname verification during the TLS handshake. An attacker positioned to intercept network traffic between the affected component and its Elasticsearch/OpenSearch backend (for example, via DNS spoofing, BGP hijacking, or a compromised host on a shared network segment) could impersonate the backend, intercept the Basic authentication credentials sent to it, read or tamper with process data (including variables and process instance data) in transit, and inject forged responses back to the application. Exploitation requires this man-in-the-middle network position; it does not require bypassing authentication on the application's own API. Camunda is not aware of any known exploitation of this vulnerability.

How to determine if the installation is affected​

You are using:

  • Camunda Zeebe ≤ 8.7.37
  • Camunda Tasklist ≤ 8.7.37
  • Camunda Operate ≤ 8.7.37

Products affected​

  • Camunda Web Modeler

Impact​

The application was vulnerable to CVE-2026-54399, where a flaw in the HTTP/1.1 message parser in Apache HttpComponents Core allows a remote attacker to cause a denial of service through memory exhaustion by sending messages with an excessive number of headers or excessively long headers.

The vulnerable library is only used in outgoing HTTP requests from Web Modeler to the Camunda 8 Orchestration Cluster API. To exploit the vulnerability, an attacker would need to be able to control or intercept the API responses through a prior attack. Web Modeler's inbound HTTP requests are handled by a different library, so the vulnerable code path is not reachable from external, untrusted client traffic.

How to determine if the installation is affected​

  • You are using Web Modeler Self-Managed ≤ 8.9.5, ≤ 8.8.16, or ≤ 8.7.23.

Solution​

Camunda has provided the following releases which contain the fix:

Impact​

The application was vulnerable to CVE-2026-13006, an arbitrary code execution vulnerability in the logback-core library used by Camunda Optimize. An attacker who already has write access to the Logback configuration file, or the ability to inject an environment variable evaluated at startup, could execute arbitrary code in the Optimize process. Exploitation also requires the Janino library on the classpath and a Logback configuration that uses conditional (<if>) processing, both of which are present in Camunda Optimize. This vulnerability is not remotely exploitable; it requires an attacker to already hold privileged local access to the deployment.

Camunda Zeebe

Impact​

When parsing unknown fields in the Protobuf Java Lite and Full library, a maliciously crafted message can cause a StackOverflow error and lead to a program crash.

  • As Zeebe makes extensive use of Protobuf, this could lead to denial-of-service (DoS) issues on the server side.
  • This issue allows an attacker to send specific payloads that will always result in StackOverflowException. This could lead to Zeebe Gateway performance issues and affect system availability.

  • GET /v1/tasks/{taskId}
  • POST /v1/tasks/search
  • POST /v1/tasks/{taskId}/variables/search
  • POST /v1/forms/{formId}
