CVE-2026-47133

ClearanceKit on macOS stores per-record policy data in /Library/Application Support/clearancekit/store.db with ECDSA signatures in data_signatures. Prior to 5.0.10, the signed payload lacks a monotonic counter or freshness binding, allowing an attacker who can modify store.db and the matching dat...

CVE-2026-47133 ClearanceKit's signed policy tables lack monotonic counter, allowing replay of older legitimately-signed snapshots

ClearanceKit intercepts file-system access events on macOS and enforces per-process access policies. Prior to version 5.0.10, each table in the on-disk SQLite policy store /Library/Application Support/clearancekit/store.db is verified using an ECDSA signature stored in the datasignatures table. T...
