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.

The advisory is shared at github.com. This vulnerability is known as CVE-2026-40191 since 04/09/2026. The exploitation appears to be easy. An attack has to be approached locally. Neither technical details nor an exploit are publicly available.
