What is CVE-2017-2611?

Jenkins versions prior to 2.44 and 2.32.2 exhibit a security flaw due to inadequate permission checks on periodic processes. Specifically, endpoints such as /workspaceCleanup and /fingerprintCleanup allow users with mere read access to trigger these maintenance processes. This could inadvertently lead to increased load on both the Jenkins master and agent nodes, impacting overall system performance.

Affected Version(s)

jenkins jenkins 2.44

jenkins jenkins 2.32.2
