ClearanceKit: Ad-hoc signed binaries can spoof Apple process identities in the global allowlist

Published Apr 21, 2026 · Updated Apr 21, 2026 · Assigned by GitHub_M

Description

ClearanceKit intercepts file-system access events on macOS and enforces per-process access policies. Prior to 5.0.5, ClearanceKit incorrectly treats a process with an empty Team ID and a non-empty Signing ID as an Apple platform binary. This bug allows a malicious software to impersonate an apple process in the global allowlist, and access all protected files. This vulnerability is fixed in 5.0.5.
