CVE-2026-40191
MEDIUMClearanceKit Endpoint Security Events - Policy Bypass
Title source: manualDescription
ClearanceKit intercepts file-system access events on macOS and enforces per-process access policies. Prior to 5.0.4-beta-1f46165, ClearanceKit's Endpoint Security event handler only checked the source path of dual-path file operations against File Access Authorization (FAA) rules and App Jail policies. The destination path was ignored entirely. This allowed any local process to bypass file-access protection by using rename, link, copyfile, exchangedata, or clone operations to place or replace files inside protected directories. This vulnerability is fixed in 5.0.4-beta-1f46165.
