## Description

Jenkins before versions 2.44, 2.32.2 is 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.
