Vulnerability Description
ClearanceKit intercepts file-system access events on macOS and enforces per-process access policies. Prior to version 4.2.14, two related startup defects created a window during which only the single compile-time baseline rule was enforced by opfilter. All managed (MDM-delivered) and user-defined file-access rules were not applied until the user interacted with policies through the GUI, triggering a policy mutation over XPC. This issue has been patched in version 4.2.14.
