{"id":"CVE-2026-2270","published":"2026-10-26T23:17:00.010","lastModified":"2026-10-27T00:17:19.210","description":"A confused deputy attack exists in the StatefulSet controller that allows a user with namespace-scoped write permissions on StatefulSet and ControllerRevision objects to create a cross-namespace pod. An attacker exploiting this vulnerability would have full control over the resulting pod’s metadata and specification, including namespace selection. Note that the cross-namespace pod will be immediately deleted by the garbage collector unless the attacker is able to construct a valid StatefulSet OwnerReference. This would require referencing the UID of an existing StatefulSet in the victim’s namespace.","cvssScore":5.9,"cvssSeverity":"MEDIUM","cvssVector":"CVSS:3.1/AV:N/AC:H/PR:H/UI:N/S:U/C:H/I:H/A:N","cwes":["CWE-639"],"vendors":[],"products":[],"references":[{"url":"https://github.com/kubernetes/kubernetes/issues/142097","tags":[]},{"url":"https://groups.google.com/g/kubernetes-security-announce/c/wv0iV-Rcmj4","tags":[]},{"url":"http://www.openwall.com/lists/oss-security/2026/09/23/35","tags":[]}],"exploitRefs":[{"url":"https://github.com/kubernetes/kubernetes/issues/142097","tags":[]}],"hasPoc":true,"ai":null}
