CVE-2026-84671 is a path-traversal vulnerability in Jenkins File Parameter Plugin 425.v3fa_801681b_5e and earlier. The plugin handles uploaded file parameters through Stapler data binding and uses an insufficiently validated parameter name as a filesystem path. An authenticated attacker can cause files to be written to arbitrary locations on the Jenkins controller filesystem, potentially enabling remote code execution.
