CVE-2025-29891: Camel support Apache Camel Message Header Injection Vulnerability
MODERATECVE-2025-29891 is a MODERATE (CVSS 4.2) apache camel message header injection vulnerability (CWE-164: Improper Neutralization of Internal Special Elements) affecting Camel support libraries in the Maven ecosystem. The issue involves apache camel message header injection through request parameters. Remediation is available by upgrading affected packages to version 3.22.4, 4.10.2, 4.8.5.
CVE-2025-29891 at a Glance
Security Impact
CVSS: 4.2
The security impact metrics below are parsed directly from the CVSS v3.1 vector string (CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:N/I:L/A:L).
How to Fix CVE-2025-29891
To remediate this vulnerability, upgrade all affected Camel support dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.
<dependency>
<groupId>org.apache.camel</groupId>
<artifactId>camel-support</artifactId>
<version>3.22.4</version>
</dependency>
<dependency>
<groupId>org.apache.camel</groupId>
<artifactId>camel-support</artifactId>
<version>4.10.2</version>
</dependency>
<dependency>
<groupId>org.apache.camel</groupId>
<artifactId>camel-support</artifactId>
<version>4.8.5</version>
</dependency>
Run the following command in your project directory to verify that all resolved dependencies use the patched release:
mvn dependency:tree -Dincludes=org.apache.camel
How to Check if You Are Affected
To determine whether your Java application is affected by CVE-2025-29891, inspect your build dependencies using the Maven Dependency Plugin:
mvn dependency:tree -Dincludes=org.apache.camel
Analyze the terminal output to locate any version of Camel support in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 3.22.4), your application is affected.
Note: The mvn dependency:tree -Dincludes=org.apache.camel command inspects the resolved dependency graph declared in your project's POM files; it does not perform automated security scanning or inspect runtime dynamic classpaths. Always verify runtime container classpaths and shaded JARs.
Technical Details
Vulnerability Mechanism & Technical Analysis
This vulnerability is classified under CWE-164: Improper Neutralization of Internal Special Elements, where the product receives input from an upstream component, but it does not neutralize or incorrectly neutralizes internal special elements that could be interpreted in unexpected ways when they are sent to a downstream component. In Camel support, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Like in CVE-2025-27636, exploitation is only possible if the Camel route uses particular vulnerable components.",
