An attacker exploiting this vulnerability would have full control over the resulting pod\u2019s 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\u2019s namespace."}], "lastModified": "2026-10-29T11:17:32.597", "sourceIdentifier": "jordan@liggitt.net"}
