Description OSIDB Bzimport 2026-09-02 16:04:02 UTC 
In Jenkins 2.579 and earlier, LTS 2.568.2 and earlier, the build CLI command does not check the Item/Cancel permission when using the -s flag to cancel a build triggered to wait for completion, allowing attackers with Item/Build permission to cancel builds started by other users.
