Jenkins before versions before 2.44 are vulnerable to an insufficient permission check for periodic processes (SECURITY-389). The URLs /workspaceCleanup and /fingerprintCleanup did not perform permission checks, allowing users with read access to Jenkins to trigger these background processes (that are otherwise performed daily), possibly causing additional load on Jenkins master and agents.
