How to Fix CVE-2026-57281

To remediate this vulnerability, upgrade all affected Script security 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:script-security fixed: 1402.1405.vc96e74964250 
<dependency>
    <groupId>org.jenkins-ci.plugins</groupId>
    <artifactId>script-security</artifactId>
    <version>1402.1405.vc96e74964250</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-2026-57281, 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 Script security in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1402.1405.vc96e74964250), 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-917: Improper Neutralization of Special Elements used in an Expression Language Statement ('Expression Language Injection'), where the product constructs all or part of an expression language (el) statement in a framework such as a java server page (jsp) using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended el statement before it is executed. In Script security, 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 Script Security Plugin 1402.v94c9ce464861 and earlier does not reject Groovy AST transformation annotations such as @CompileStatic and @TypeChecked that carry an extensions member, which causes Groovy to load and execute a script from the classpath at compile time, before the sandbox is applied. This may allow attackers able to define and run sandboxed scripts to execute code outside the sandbox, in the rare case that a suitable Groovy script is present on the classpath of the component that evaluates the script. The Jenkins security team has been unable to identify any Groovy source files in Jenkins core or plugins that would allow attackers to execute dangerous code. While the severity of this issue is declared as High due to the potential impact, successful exploitation is considered very unlikely. Script Security Plugin 1402.1405.vc96e74964250 rejects any annotation carrying an extensions member during sandbox compilation, before Groovy can resolve or execute the referenced script.
