{"cve":"CVE-2026-53999","nvd":{"published":"2026-10-14T19:17:17.340","modified":"2026-10-16T20:04:29.760","status":"Deferred","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.","cvss_v4":null,"cvss_v3":{"version":"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},"cwes":["CWE-20","CWE-441"],"references":["https://github.com/radius-project/radius/commit/c4174fc205b838d5eab4f64b4909001ab08c0587","https://github.com/radius-project/radius/pull/11967","https://github.com/radius-project/radius/releases/tag/v0.58.0","https://github.com/radius-project/radius/security/advisories/GHSA-fp5j-4fj2-4jvq","https://github.com/radius-project/radius/security/advisories/GHSA-fp5j-4fj2-4jvq"],"products":[],"source":"nvd","synced_at":"2026-10-19T23:00:53.604569364+00:00"},"epss":{"cve":"CVE-2026-53999","score":0.0034,"percentile":0.27286,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-fp5j-4fj2-4jvq","url":"https://osv.dev/vulnerability/GHSA-fp5j-4fj2-4jvq","summary":"Radius Controller May Delete a Container Resource via an Injected Deployment Annotation (Multi-Tenant Installs)","modified":"2026-06-25T19:56:28.409937043Z","packages":[{"ecosystem":"Go","name":"github.com/radius-project/radius","purl":"pkg:golang/github.com/radius-project/radius","ranges":["<0.58.0"],"fixed":["0.58.0"]}]},{"id":"GO-2026-5373","url":"https://osv.dev/vulnerability/GO-2026-5373","summary":"Radius Controller May Delete a Container Resource via an Injected Deployment Annotation (Multi-Tenant Installs) in github.com/radius-project/radius","modified":"2026-06-25T19:45:19.064976833Z","packages":[{"ecosystem":"Go","name":"github.com/radius-project/radius","purl":"pkg:golang/github.com/radius-project/radius","ranges":["<0.58.0"],"fixed":["0.58.0"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
