CVE-2026-40599: Craigjbass Clearancekit

High severity, CVSS 7.1. EPSS: 0.1% chance of exploitation in the next 30 days.

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.

Affected products

• Craigjbass Clearancekit: before 5.0.5 (fixed in 5.0.5)
