CVE-2026-70432Network attack vector

Controller code execution via non-POST form validation

Published Aug 5, 2026 · Updated Aug 5, 2026

CSRF in Jenkins Multijob Plugin 669.v9d96a_d9c71b_0 and earlier allows attackers to execute arbitrary code in the controller JVM. The affected form-validation endpoint accepts non-POST requests, allowing a cross-origin request to reach code evaluation without Jenkins's POST protection. Jenkins has not identified the endpoint or stated the permission needed to reach it; successful exploitation runs code with controller JVM privileges.
