{"id":"CVE-2026-47133","state":"PUBLISHED","title":"ClearanceKit's signed policy tables lack monotonic counter, allowing replay of older legitimately-signed snapshots","description":"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 `data_signatures` table. The signed payload contains only the canonical row content, with no version counter or freshness binding. An attacker who can write `store.db` and the matching `data_signatures` row — feasible during the opfilter-update window when the Endpoint Security filter is offline, or via offline-boot / decrypted-backup scenarios — can substitute a previously-captured legitimately-signed snapshot. opfilter accepts the older snapshot as fully valid on next boot because the existing signatures still verify. Version 5.0.10 patches the issue.","publishedAt":"2026-07-20T21:12:26.245Z","updatedAt":"2026-07-21T14:09:08.557Z","severity":{"score":6.9,"label":"Medium","version":"4.0","vector":"CVSS:4.0/AV:L/AC:L/AT:P/PR:H/UI:N/VC:N/VI:H/VA:N/SC:H/SI:H/SA:N","source":"GitHub_M"},"assigner":"GitHub_M","products":["craigjbass clearancekit"],"affected":[{"vendor":"craigjbass","product":"clearancekit","versions":[{"version":"< 5.0.10","status":"affected"}]}],"references":["https://github.com/craigjbass/clearancekit/security/advisories/GHSA-9hx3-5wp9-2qqg"],"weaknesses":["CWE-294"],"ingestedAt":"2026-10-29T20:12:07.131Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/47xxx/CVE-2026-47133.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-47133","state":"PUBLISHED","datePublished":"2026-07-20T21:12:26.245Z","dateUpdated":"2026-07-21T14:09:08.557Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2026-05-18T19:50:18.695Z"},"containers":{"cna":{"title":"ClearanceKit's signed policy tables lack monotonic counter, allowing replay of older legitimately-signed snapshots","descriptions":[{"lang":"en","value":"ClearanceKit intercepts file-system access events on macOS and enforces per-process access policies.
