{"id":"OESA-2026-4835","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":"2026-11-11T12:45:11.668159121Z","published":"2026-11-11T12:26:40Z","upstream":["CVE-2026-2270"],"database_specific":{"severity":"Medium"},"references":[{"type":"ADVISORY","url":"https://www.openeuler.org/zh/security/security-bulletins/detail/?id=openEuler-SA-2026-4835"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-2270"}],"affected":[{"package":{"name":"kubernetes","ecosystem":"openEuler:22.03-LTS-SP4","purl":"pkg:rpm/openEuler/kubernetes&distro=openEuler-22.03-LTS-SP4"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.20.2-35.oe2203sp4"}]}],"ecosystem_specific":{"src":["kubernetes-1.20.2-35.oe2203sp4.src.rpm"],"x86_64":["kubernetes-1.20.2-35.oe2203sp4.x86_64.rpm","kubernetes-client-1.20.2-35.oe2203sp4.x86_64.rpm","kubernetes-help-1.20.2-35.oe2203sp4.x86_64.rpm","kubernetes-kubeadm-1.20.2-35.oe2203sp4.x86_64.rpm","kubernetes-kubelet-1.20.2-35.oe2203sp4.x86_64.rpm","kubernetes-master-1.20.2-35.oe2203sp4.x86_64.rpm","kubernetes-node-1.20.2-35.oe2203sp4.x86_64.rpm"],"aarch64":["kubernetes-1.20.2-35.oe2203sp4.aarch64.rpm","kubernetes-client-1.20.2-35.oe2203sp4.aarch64.rpm","kubernetes-help-1.20.2-35.oe2203sp4.aarch64.rpm","kubernetes-kubeadm-1.20.2-35.oe2203sp4.aarch64.rpm","kubernetes-kubelet-1.20.2-35.oe2203sp4.aarch64.rpm","kubernetes-master-1.20.2-35.oe2203sp4.aarch64.rpm","kubernetes-node-1.20.2-35.oe2203sp4.aarch64.rpm"]},"database_specific":{"source":"https://repo.openeuler.org/security/data/osv/OESA-2026-4835.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"}]}
