Name of the Vulnerable Software and Affected Versions ClearanceKit versions prior to 5.0.6

Description The opfilter Endpoint Security system extension (bundle ID 'uk.craigbass.clearancekit.opfilter') can be suspended using SIGSTOP or kill -STOP, or terminated using SIGKILL/SIGTERM, by any process with root privileges. When the extension is suspended, all AUTH Endpoint Security events time out and default to allow, which silently disables the enforcement of file-access policies.
