{"id":"OESA-2026-4836","summary":"kubernetes security update","details":"Container cluster management.\r\n\r\nSecurity Fix(es):\n\nA 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.(CVE-2026-2270)","modified":"2026-11-11T12:45:11.716709170Z","published":"2026-11-11T12:26:41Z","upstream":["CVE-2026-2270"],"database_specific":{"severity":"Medium"},"references":[{"type":"ADVISORY","url":"https://www.openeuler.org/zh/security/security-bulletins/detail/?id=openEuler-SA-2026-4836"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-2270"}],"affected":[{"package":{"name":"kubernetes","ecosystem":"openEuler:24.03-LTS-SP1","purl":"pkg:rpm/openEuler/kubernetes&distro=openEuler-24.03-LTS-SP1"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.29.1-21.oe2403sp1"}]}],"ecosystem_specific":{"x86_64":["kubernetes-1.29.1-21.oe2403sp1.x86_64.rpm","kubernetes-client-1.29.1-21.oe2403sp1.x86_64.rpm","kubernetes-help-1.29.1-21.oe2403sp1.x86_64.rpm","kubernetes-kubeadm-1.29.1-21.oe2403sp1.x86_64.rpm","kubernetes-kubelet-1.29.1-21.oe2403sp1.x86_64.rpm","kubernetes-master-1.29.1-21.oe2403sp1.x86_64.rpm","kubernetes-node-1.29.1-21.oe2403sp1.x86_64.rpm"],"aarch64":["kubernetes-1.29.1-21.oe2403sp1.aarch64.rpm","kubernetes-client-1.29.1-21.oe2403sp1.aarch64.rpm","kubernetes-help-1.29.1-21.oe2403sp1.aarch64.rpm","kubernetes-kubeadm-1.29.1-21.oe2403sp1.aarch64.rpm","kubernetes-kubelet-1.29.1-21.oe2403sp1.aarch64.rpm","kubernetes-master-1.29.1-21.oe2403sp1.aarch64.rpm","kubernetes-node-1.29.1-21.oe2403sp1.aarch64.rpm"],"src":["kubernetes-1.29.1-21.oe2403sp1.src.rpm"]},"database_specific":{"source":"https://repo.openeuler.org/security/data/osv/OESA-2026-4836.json"}}],"schema_version":"1.9.2","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:H/UI:N/S:U/C:H/I:H/A:N"}]}
