CVE-2025-64132Network attack vector

Disclosure and build execution via unchecked MCP tools

Published Oct 29, 2025 · Updated Oct 29, 2025

Missing authorization in Jenkins MCP Server Plugin 0.84.v50ca_24ef83f2 and earlier allows remote authenticated users to expose data or trigger builds. The triggerBuild method omits Item/Build enforcement, getJobScm returns SCM details without Item/Extended Read, and getStatus lists clouds without Overall/Read. Item/Read access suffices for job actions and SCM disclosure, while cloud-name disclosure requires no Overall/Read permission.
