How to Fix CVE-2025-64132

To remediate this vulnerability, upgrade all affected Mcp server 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:mcp-server fixed: 0.86.v7d3355e6a 
<dependency>
    <groupId>io.jenkins.plugins</groupId>
    <artifactId>mcp-server</artifactId>
    <version>0.86.v7d3355e6a</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-2025-64132, 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 Mcp server in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 0.86.v7d3355e6a), 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-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 Mcp server, 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 MCP Server Plugin 0.84.v50ca_24ef83f2 and earlier does not perform permission checks in several MCP tools. This allows to do the following: - Attackers with Item/Read permission can obtain information about the configured SCM in a job despite lacking Item/Extended Read permission (`getJobScm`). - Attackers with Item/Read permission can trigger new builds of a job despite lacking Item/Build permission (`triggerBuild`). - Attackers without Overall/Read permission can retrieve the names of configured clouds (`getStatus`). MCP Server Plugin 0.86.v7d3355e6a_a_18 performs permission checks for the affected MCP tools.
