{"schema":"threatline.record/2","record":{"id":"CVE-2026-53999","aliases":["GHSA-fp5j-4fj2-4jvq","GO-2026-5373"],"summary":"Radius Controller May Delete a Container Resource via an Injected Deployment Annotation (Multi-Tenant Installs)","details":"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.","categories":["Libraries & packages"],"product":"radius","vendor":"radius-project","ecosystem":"Go","affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-53999","source_modified_at":"2026-10-14T19:42:38.965Z","fetched_at":"2026-10-23T18:48:36.087640Z","product":"radius","vendor":"radius-project","versions":[{"status":"affected","version":"< 0.58.0"}],"defaultStatus":null},{"source":"GitHub Advisory Database","source_url":"https://github.com/radius-project/radius/security/advisories/GHSA-fp5j-4fj2-4jvq","source_modified_at":"2026-06-11T23:10:58Z","fetched_at":"2026-10-24T10:48:42.330819Z","package":{"name":"radius","ecosystem":null},"range":"Radius 0.57.1 and earlier versions"},{"source":"OSV","source_url":"https://osv.dev/vulnerability/GHSA-fp5j-4fj2-4jvq","source_modified_at":"2026-06-25T19:56:28.409937043Z","fetched_at":"2026-10-23T18:48:36.087640Z","package":{"ecosystem":"Go","name":"github.com/radius-project/radius","purl":"pkg:golang/github.com/radius-project/radius"},"ranges":[{"events":[{"introduced":"0"},{"fixed":"0.58.0"}],"type":"SEMVER"}],"versions":[]}],"fixed_versions":[{"source":"GitHub Advisory Database","source_url":"https://github.com/radius-project/radius/security/advisories/GHSA-fp5j-4fj2-4jvq","source_modified_at":"2026-06-11T23:10:58Z","fetched_at":"2026-10-24T10:48:42.330819Z","package":{"name":"radius","ecosystem":null},"version":"0.58.0"},{"source":"OSV","source_url":"https://osv.dev/vulnerability/GHSA-fp5j-4fj2-4jvq","source_modified_at":"2026-06-25T19:56:28.409937043Z","fetched_at":"2026-10-23T18:48:36.087640Z","package":{"ecosystem":"Go","name":"github.com/radius-project/radius","purl":"pkg:golang/github.com/radius-project/radius"},"version":"0.58.0"}],"cvss":7.7,"severity":"High","kev":{"listed":false},"epss":{"probability":0.0034,"percentile":0.26332,"score_date":"2026-10-23"},"published_at":"2026-10-14T18:39:25.344Z","modified_at":"2026-10-14T19:42:38.965Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-53999","fetched_at":"2026-10-23T18:48:36.087640Z","source_modified_at":"2026-10-14T19:42:38.965Z"},{"source":"GitHub Advisory Database","url":"https://github.com/radius-project/radius/security/advisories/GHSA-fp5j-4fj2-4jvq","fetched_at":"2026-10-24T10:48:42.330819Z","source_modified_at":"2026-06-11T23:10:58Z"},{"source":"OSV","url":"https://osv.dev/vulnerability/GHSA-fp5j-4fj2-4jvq","fetched_at":"2026-10-23T18:48:36.087640Z","source_modified_at":"2026-06-25T19:56:28.409937043Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-53999","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","GitHub Advisory Database","OSV","EPSS"],"references":[{"source":"CVE List","url":"https://github.com/radius-project/radius/security/advisories/GHSA-fp5j-4fj2-4jvq","tags":["exploit"]},{"source":"CVE List","url":"https://github.com/radius-project/radius/pull/11967","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/radius-project/radius/commit/c4174fc205b838d5eab4f64b4909001ab08c0587","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/radius-project/radius/releases/tag/v0.58.0","tags":["x_refsource_MISC"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","ssvc":{"exploitation":"poc","automatable":"no","technical_impact":"partial","assessed_at":"2026-10-14T19:42:17.591600Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":"ecosystem","confidence":"heuristic","reviewed":false},"change_timestamp":"2026-10-14T19:42:38.965Z","content_hash":"59fb15de6590dfd690ed03ac8833eb61d08f68498c6680e7e21ed1fc5dee97b5"}}
