CVE-2022-45394Network attack vector

Build-log deletion via unchecked HTTP handler

Published Nov 15, 2022 · Updated Apr 30, 2025

Missing authorization in Jenkins Delete log Plugin 1.0 and earlier allows remote authenticated users to delete build logs over HTTP. The LogDelete.doDelete handler accepts Submit=Yes and calls delete() on build and matrix-run log files without checking Item permissions. Item/Read access is sufficient, and exploitation permanently removes build-output records without altering jobs or executing code.
