How to Fix CVE-2025-31722

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

org.jenkins-ci.plugins:templating-engine fixed: 2.5.4 
<dependency>
    <groupId>org.jenkins-ci.plugins</groupId>
    <artifactId>templating-engine</artifactId>
    <version>2.5.4</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=org.jenkins-ci.plugins

How to Check if You Are Affected

To determine whether your Java application is affected by CVE-2025-31722, inspect your build dependencies using the Maven Dependency Plugin:

mvn dependency:tree -Dincludes=org.jenkins-ci.plugins

Analyze the terminal output to locate any version of Templating engine in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 2.5.4), your application is affected.

Note: The mvn dependency:tree -Dincludes=org.jenkins-ci.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-94: Improper Control of Generation of Code ('Code Injection'), where the product constructs all or part of a code segment using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the syntax or behavior of the intended code segment. In Templating engine, 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 Templating Engine Plugin allows defining libraries both in the global configuration, as well as scoped to folders containing the pipelines using them. While libraries in the global configuration can only be set up by administrators and can therefore be trusted, libraries defined in folders can be configured by users with Item/Configure permission. In Templating Engine Plugin 2.5.3 and earlier, libraries defined in folders are not subject to sandbox protection. This vulnerability allows attackers with Item/Configure permission to execute arbitrary code in the context of the Jenkins controller JVM. In Templating Engine Plugin 2.5.4, libraries defined in folders are subject to sandbox protection.
