How to Fix CVE-2026-57301

To remediate this vulnerability, upgrade all affected Jenkins OWASP ZAP Plugin 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:zapper fixed: Latest secure release 
<dependency>
    <groupId>org.jenkins-ci.plugins</groupId>
    <artifactId>zapper</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=org.jenkins-ci.plugins

How to Check if You Are Affected

To determine whether your Java application is affected by CVE-2026-57301, 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 Jenkins OWASP ZAP Plugin 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=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-610: Externally Controlled Reference to a Resource in Another Sphere, where the product uses an externally controlled name or reference that resolves to a resource that is outside of the intended control sphere. In Jenkins OWASP ZAP Plugin, 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 OWASP ZAP Plugin 1.0.7 and earlier does not support distributed builds, causing the file operations and build process of its "Automatically build ZAP" feature to be performed on the Jenkins controller rather than on the agent the build is assigned to. This allows attackers with Item/Configure permission to configure the feature to build an attacker-controlled project, executing arbitrary code on the Jenkins controller and bypassing any restriction confining the build to a specific agent. As of publication of this advisory, there is no fix.
