Craigjbass · Clearancekit · CVE-2026-34218
**Name of the Vulnerable Software and Affected Versions**
ClearanceKit versions prior to 4.2.14
**Description**
ClearanceKit intercepts file-system access events on macOS to enforce per-process access policies. Startup defects create a window where only the compile-time baseline rule is enforced by opfilter. During this period, user-defined and managed (MDM-delivered) file-access rules are not applied until a policy mutation over XPC is triggered by the user interacting with policies through the GUI.
**Recommendations**
Update to version 4.2.14.
