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."}],"source":{"advisory":"GHSA-9hx3-5wp9-2qqg","discovery":"UNKNOWN"}},"adp":[{"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2026-07-21T14:08:57.775610Z","id":"CVE-2026-47133","options":[{"Exploitation":"none"},{"Automatable":"no"},{"Technical Impact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-07-21T14:09:08.557Z"}}]}}
