How to Fix CVE-2025-64145

To remediate this vulnerability, upgrade all affected Byteguard build actions dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

io.jenkins.plugins:byteguard-build-actions fixed: Latest secure release 
<dependency>
    <groupId>io.jenkins.plugins</groupId>
    <artifactId>byteguard-build-actions</artifactId>
    <version>Latest secure release</version>
</dependency>
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

mvn dependency:tree -Dincludes=io.jenkins.plugins

How to Check if You Are Affected

To determine whether your Java application is affected by CVE-2025-64145, inspect your build dependencies using the Maven Dependency Plugin:

mvn dependency:tree -Dincludes=io.jenkins.plugins

Analyze the terminal output to locate any version of Byteguard build actions in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than the patched release), your application is affected.

Note: The mvn dependency:tree -Dincludes=io.jenkins.plugins 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-311: Missing Encryption of Sensitive Data, where the product does not encrypt sensitive or critical information before storage or transmission. In Byteguard build actions, 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.

Source Advisory Statement

Jenkins ByteGuard Build Actions Plugin 1.0 and earlier stores API tokens unencrypted in job `config.xml` files on the Jenkins controller as part of its configuration. These tokens can be viewed by users with Item/Extended Read permission or access to the Jenkins controller file system. Additionally, the job configuration form does not mask these credentials, increasing the potential for attackers to observe and capture them. As of publication of this advisory, there is no fix.
