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.","state":0,"publishedAt":null,"modifiedAt":null,"affected":[],"metrics":[{"system":"EUVD CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H","score":9.9,"severity":null}],"references":["https://github.com/argoproj/argo-cd/security/advisories/GHSA-fmxq-cgp8-87wp","https://github.com/argoproj/argo-cd/commit/1149cdc6e932208c4402183cc3d7b7485239940c","https://github.com/argoproj/argo-cd/commit/4bc8085b0a6d2296b849539d3d09fc7be7a4a511","https://github.com/argoproj/argo-cd/commit/7f0a05834b05103d69d7c150e1ee36541b314696","https://github.com/argoproj/argo-cd/commit/d5dd7019ee65be8895133fe4df554e28074242c4","https://github.com/argoproj/argo-cd/releases/tag/v3.3.15","https://github.com/argoproj/argo-cd/releases/tag/v3.4.10","https://github.com/argoproj/argo-cd/releases/tag/v3.5.4","https://github.com/argoproj/argo-cd/releases/tag/v3.6.0-rc2"],"sourceUrl":"https://euvd.enisa.europa.eu/vulnerability/EUVD-2026-98917","license":"ENISA EUVD · source terms and attribution apply","enrichment":{"sourceStatus":null,"weaknesses":[],"productCriteria":[],"sourceDates":{"datePublished":"Oct 13, 2026, 4:26:47 PM","dateUpdated":"Oct 14, 2026, 3:29:55 PM"},"relatedAdvisories":[{"id":"RHSA-2026:77269","title":"Red Hat Security Advisory: Red Hat OpenShift GitOps v1.21.5 security update","vulnerabilityIds":["CVE-2026-33818","CVE-2026-41178","CVE-2026-50162","CVE-2026-56852","CVE-2026-56854","CVE-2026-77459"]},{"id":"RHSA-2026:77273","title":"Red Hat Security Advisory: Red Hat OpenShift GitOps v1.20.8 security update","vulnerabilityIds":["CVE-2026-33818","CVE-2026-50162","CVE-2026-56852","CVE-2026-56853","CVE-2026-56854","CVE-2026-56859","CVE-2026-56860","CVE-2026-56862","CVE-2026-77459"]},{"id":"RHSA-2026:77267","title":"Red Hat Security Advisory: Red Hat OpenShift GitOps v1.22.1 security update","vulnerabilityIds":["CVE-2026-33818","CVE-2026-77459"]}],"note":"EUVD source date text has no stated timezone and is retained without inventing a UTC instant.
