How to Fix CVE-2025-64131

To remediate this vulnerability, upgrade all affected Saml 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:saml fixed: 4.583.585.v22ccc1139f55 
<dependency>
    <groupId>org.jenkins-ci.plugins</groupId>
    <artifactId>saml</artifactId>
    <version>4.583.585.v22ccc1139f55</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-2025-64131, 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 Saml in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 4.583.585.v22ccc1139f55), 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-294: Authentication Bypass by Capture-replay, where a capture-replay flaw exists when the design of the product makes it possible for a malicious user to sniff network traffic and bypass authentication by replaying it to the server in question to the same effect as the original message (or with minor changes). In Saml, 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 SAML Plugin 4.583.vc68232f7018a_ and earlier does not implement a replay cache. This allows attackers able to obtain information about the SAML authentication flow between a user’s web browser and Jenkins to replay those requests, authenticating to Jenkins as that user. SAML Plugin 4.583.585.v22ccc1139f55 implements a replay cache that rejects replayed requests.
