How to Fix CVE-2026-57286

To remediate this vulnerability, upgrade all affected Git parameter 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.tools:git-parameter fixed: 462.463 
<dependency>
    <groupId>org.jenkins-ci.tools</groupId>
    <artifactId>git-parameter</artifactId>
    <version>462.463</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.tools

How to Check if You Are Affected

To determine whether your Java application is affected by CVE-2026-57286, inspect your build dependencies using the Maven Dependency Plugin:

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

Analyze the terminal output to locate any version of Git parameter in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 462.463), your application is affected.

Note: The mvn dependency:tree -Dincludes=org.jenkins-ci.tools 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-862: Missing Authorization, where the product does not perform an authorization check when an actor attempts to access a resource or perform an action. In Git parameter, 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 Git Parameter Plugin 462.vdcf3df2ed2ca_ and earlier does not perform a permission check in an HTTP endpoint that populates the list of values for Git parameters by querying the SCM configured on a job, using the SCM credentials configured in Jenkins. This allows attackers with Item/Read permission to obtain information about the SCM repository used by a job they would otherwise be unable to access, such as branch names, tag names, and revision metadata. Git Parameter Plugin 462.463.v496a_59f698e5 requires Item/Build permission to populate the list of values for Git parameters.
