From 2.10.0 until 3.3.15, 3.4.10, 3.5.4, and 3.6.0-rc2, Argo CD creates PostDelete resource hooks without applying the AppProject destination and resource authorization checks used during ordinary synchronization. The omitted checks include cluster-scoped and namespaced resource allow/deny lists. A user who can write to an Application's Git repository can commit a delete hook targeting a forbidden namespace, server, group, kind, or resource name, and deletion of the Application causes the application-controller to create that resource with its destination-cluster credentials. The reachable impact is bounded by the controller's cluster access but can include cluster-scoped resources, disallowed namespaces, persistent hook objects, and secondary objects created by a hook Job. PreSync, Sync, PostSync, and SyncFail hooks continue to use the normal project checks. This issue is fixed in versions 3.3.15, 3.4.10, 3.5.4, and 3.6.0-rc2."}],"affected":[{"source":"security-advisories@github.com","affectedData":[{"vendor":"argoproj","product":"argo-cd","versions":[{"version":">= 2.10.0, <= 2.14.21","status":"affected"},{"version":">= 3.0.0, < 3.3.15","status":"affected"},{"version":">= 3.4.0, < 3.4.10","status":"affected"},{"version":">= 3.5.0, < 3.5.4","status":"affected"},{"version":">= 3.6.0-rc1, < 3.6.0-rc2","status":"affected"}]}]}],"metrics":{"cvssMetricV31":[{"source":"security-advisories@github.com","type":"Secondary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H","baseScore":9.9,"baseSeverity":"CRITICAL","attackVector":"NETWORK","attackComplexity":"LOW","privilegesRequired":"LOW","userInteraction":"NONE","scope":"CHANGED","confidentialityImpact":"HIGH","integrityImpact":"HIGH","availabilityImpact":"HIGH"},"exploitabilityScore":3.1,"impactScore":6.0}],"ssvcV203":[{"source":"134c704f-9b21-4f2e-91b3-4a467353bcc0","ssvcData":{"timestamp":"2026-10-14T15:27:27.557503Z","id":"CVE-2026-77459","options":[{"exploitation":"none"},{"automatable":"no"},{"technicalImpact":"total"}],"role":"CISA Coordinator","version":"2.0.3"}}]},"weaknesses":[{"source":"security-advisories@github.com","type":"Secondary","description":[{"lang":"en","value":"CWE-863"}]}],"references":[{"url":"https://github.com/argoproj/argo-cd/commit/1149cdc6e932208c4402183cc3d7b7485239940c","source":"security-advisories@github.com"},{"url":"https://github.com/argoproj/argo-cd/commit/4bc8085b0a6d2296b849539d3d09fc7be7a4a511","source":"security-advisories@github.com"},{"url":"https://github.com/argoproj/argo-cd/commit/7f0a05834b05103d69d7c150e1ee36541b314696","source":"security-advisories@github.com"},{"url":"https://github.com/argoproj/argo-cd/commit/d5dd7019ee65be8895133fe4df554e28074242c4","source":"security-advisories@github.com"},{"url":"https://github.com/argoproj/argo-cd/releases/tag/v3.3.15","source":"security-advisories@github.com"},{"url":"https://github.com/argoproj/argo-cd/releases/tag/v3.4.10","source":"security-advisories@github.com"},{"url":"https://github.com/argoproj/argo-cd/releases/tag/v3.5.4","source":"security-advisories@github.com"},{"url":"https://github.com/argoproj/argo-cd/releases/tag/v3.6.0-rc2","source":"security-advisories@github.com"},{"url":"https://github.com/argoproj/argo-cd/security/advisories/GHSA-fmxq-cgp8-87wp","source":"security-advisories@github.com"}]}}]}
