Prior to 0.58.0, the Kubernetes controller deserializes the user-controlled radapp.io/status annotation on a Deployment and uses its container resource identifier for deletion without confirming ownership by that Deployment. An attacker with permission to modify Deployment annotations and knowledge of a target Radius resource ID can forge radapp.io/status and set radapp.io/enabled to false, causing reconciliation to enter the privileged deletion path for another tenant's Radius-managed container resource. In a multi-tenant installation this confused-deputy condition can delete another team's recoverable container resource and disrupt service; in a single-tenant installation the impact is limited to self denial of service. The multi-tenant Radius controller reads the annotations in pkg/controller/reconciler/annotations.go and reaches the privileged delete in pkg/controller/reconciler/deployment_reconciler.go. The issue does not disclose data, grant privileges, or provide persistence. This issue is fixed in version 0.58.0.","state":0,"publishedAt":"2026-10-14T18:39:25.344+00:00","modifiedAt":"2026-10-14T19:42:38.965+00:00","affected":[{"ecosystem":"Vendor product","name":"radius","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"radius-project\",\n                    \"product\": \"radius\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< 0.58.0\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:N/I:N/A:H","score":7.7,"severity":"HIGH"}],"references":["https://github.com/radius-project/radius/security/advisories/GHSA-fp5j-4fj2-4jvq","https://github.com/radius-project/radius/pull/11967","https://github.com/radius-project/radius/commit/c4174fc205b838d5eab4f64b4909001ab08c0587","https://github.com/radius-project/radius/releases/tag/v0.58.0"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-53999","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-53999","identifiers":["CVE-2026-53999"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
