Prior to 8.0.0.2, the module ACL function `AclMain::zhAclCheck()` only checks for the presence of any \"allow\" (user or group). It never checks for explicit \"deny\" (allowed=0). As a result, administrators cannot revoke access by setting a user or group to \"deny\"; if the user is in a group that has \"allow,\" access is granted regardless of explicit denies. Version 8.0.0.2 fixes the issue."}],"source":{"advisory":"GHSA-v68v-pwc4-8p2m","discovery":"UNKNOWN"}},"adp":[{"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2026-03-20T20:20:32.279983Z","id":"CVE-2026-33302","options":[{"Exploitation":"poc"},{"Automatable":"no"},{"Technical Impact":"total"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-03-20T20:20:42.266Z"}}]}}
