How to Fix CVE-2026-57283

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

io.jenkins.plugins:pipeline-groovy-lib fixed: 4331.4333 
<dependency>
    <groupId>io.jenkins.plugins</groupId>
    <artifactId>pipeline-groovy-lib</artifactId>
    <version>4331.4333</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=io.jenkins.plugins

How to Check if You Are Affected

To determine whether your Java application is affected by CVE-2026-57283, inspect your build dependencies using the Maven Dependency Plugin:

mvn dependency:tree -Dincludes=io.jenkins.plugins

Analyze the terminal output to locate any version of Jenkins Pipeline in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 4331.4333), your application is affected.

Note: The mvn dependency:tree -Dincludes=io.jenkins.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-352: Cross-Site Request Forgery (CSRF), where the web application does not, or cannot, sufficiently verify whether a request was intentionally provided by the user who sent the request, which could have originated from an unauthorized actor. In Jenkins Pipeline, 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 Pipeline: Groovy Plugin 4331.v9d06ed4658ff and earlier does not restrict the types that can be instantiated through the Pipeline Snippet Generator, instantiating any type with a constructor annotated with @DataBoundConstructor in response to a request. This allows attackers to have Pipeline: Groovy Plugin instantiate types related to job or system configuration other than Pipeline steps. Additionally, this HTTP endpoint can be accessed using the GET method and does not require POST requests, resulting in a cross-site request forgery (CSRF) vulnerability. This allows attackers to create a script approval request attributed to another user, impersonating a trusted user when social engineering an administrator into approving a malicious script. This vulnerability has been reported through the Jenkins Bug Bounty Program sponsored by the European Commission. Pipeline: Groovy Plugin 4331.4333.v50a_b_076c5199 only instantiates Pipeline steps and metastep delegates through the Snippet Generator, and requires POST requests for the affected HTTP endpoint.
