Existing deployments of TurnKey Jenkins are still vulnerable to CVE-2015-8103, a critical issue that allows remote code execution by unauthenticated users.
Due to the seriousness of the issue new builds of TurnKey Jenkins have been published today so new deployments are not vulnerable.
Unfortunately pre-existing deployments still need to be updated manually:
