{"id":"CVE-2026-53999","published":"2026-10-14T19:17:17.340","lastModified":"2026-10-16T20:04:29.760","description":"Radius is a cloud-native, portable application platform that makes app development easier for teams building cloud-native apps. 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.","cvssScore":7.7,"cvssSeverity":"HIGH","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:N/I:N/A:H","cwes":["CWE-20","CWE-441"],"vendors":[],"products":[],"references":[{"url":"https://github.com/radius-project/radius/commit/c4174fc205b838d5eab4f64b4909001ab08c0587","tags":[]},{"url":"https://github.com/radius-project/radius/pull/11967","tags":[]},{"url":"https://github.com/radius-project/radius/releases/tag/v0.58.0","tags":[]},{"url":"https://github.com/radius-project/radius/security/advisories/GHSA-fp5j-4fj2-4jvq","tags":[]},{"url":"https://github.com/radius-project/radius/security/advisories/GHSA-fp5j-4fj2-4jvq","tags":[]}],"exploitRefs":[{"url":"https://github.com/radius-project/radius/commit/c4174fc205b838d5eab4f64b4909001ab08c0587","tags":[]},{"url":"https://github.com/radius-project/radius/pull/11967","tags":[]},{"url":"https://github.com/radius-project/radius/releases/tag/v0.58.0","tags":[]},{"url":"https://github.com/radius-project/radius/security/advisories/GHSA-fp5j-4fj2-4jvq","tags":[]},{"url":"https://github.com/radius-project/radius/security/advisories/GHSA-fp5j-4fj2-4jvq","tags":[]}],"hasPoc":true,"ai":null}
