Summary
Jenkins Templating Engine Plugin Vulnerable to Arbitrary Code Execution
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.
Impact
Untrusted input is evaluated as executable code within the application's runtime environment. Typical impact: arbitrary code execution within the application's privilege context.
CVE-2025-31722 has a CVSS score of 8.8 (High). The vector is network-reachable, low privileges required, and no user interaction. A CVSS score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether this affects your application depends on whether the vulnerable code is present and reachable in your environment. A fixed version is available (2.5.4); upgrading removes the vulnerable code path.

Kodem intelligence
Severity tells you how bad this could be in the worst case. It does not tell you whether you are exposed. Exploitability and impact are functions of runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A vulnerable package can sit in your dependency tree and never run.
Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter. Kodem's runtime-powered SCA identifies whether this CVE is reachable in your applications.

Frequently Asked Questions
- What is CVE-2025-31722? CVE-2025-31722 is a high-severity code injection vulnerability in org.jenkins-ci.plugins:templating-engine (maven), affecting versions < 2.5.4. It is fixed in 2.5.4. Untrusted input is evaluated as executable code within the application's runtime environment.
- How severe is CVE-2025-31722? CVE-2025-31722 has a CVSS score of 8.8 (High). This score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether it represents real risk in your environment depends on whether the vulnerable code is present and reachable.
- Which versions of org.jenkins-ci.plugins:templating-engine are affected by CVE-2025-31722? org.jenkins-ci.plugins:templating-engine (maven) versions < 2.5.4 is affected.
- Is there a fix for CVE-2025-31722? Yes. CVE-2025-31722 is fixed in 2.5.4. Upgrade to this version or later.
- Is CVE-2025-31722 exploitable, and should I be worried? Whether CVE-2025-31722 is exploitable in your environment depends on whether the vulnerable code is present and reachable. A CVSS score is a worst-case rating; it does not account for your specific deployment, configuration, or usage patterns. Kodem, an Intelligent Application Security platform, uses runtime intelligence to show which vulnerabilities actually execute in production, so you can focus on the ones that represent real risk.

- What actually determines whether CVE-2025-31722 is exploitable, and how bad it is? Exploitability and impact are not fixed properties of a CVE. They depend on runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A high CVSS score on a dependency that never runs is not the same as real risk. Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter.
- How do I fix CVE-2025-31722? Upgrade
org.jenkins-ci.plugins:templating-engineto 2.5.4 or later.
