{"id":"CVE-2023-1260","aliases":[],"url":"https://o3.security/vulnerability/CVE-2023-1260","summary":"kube-apiserver authentication bypass vulnerability","details":"An authentication bypass vulnerability was discovered in kube-apiserver. This issue could allow a remote, authenticated attacker who has been given permissions \"update, patch\" the \"pods/ephemeralcontainers\" subresource beyond what the default is. They would then need to create a new pod or patch one that they already have access to. This might allow evasion of SCC admission restrictions, thereby gaining control of a privileged pod.","published":"2023-09-24T03:30:20Z","modified":"2026-05-04T09:00:06.750168469Z","cvss":{"score":8,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:H/PR:H/UI:N/S:C/C:H/I:H/A:H"},"epss":{"score":0.01569,"percentile":0.74143,"asOf":"2026-09-17"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Go","name":"github.com/openshift/apiserver-library-go","fixedVersion":"0.0.0-20230621"}],"fix":{"url":"https://github.com/openshift/apiserver-library-go/commit/a994128188486d2dce99a528fbcc017d276081e0","label":"openshift/apiserver-library-go@a994128"},"references":[{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2023-1260"},{"type":"WEB","url":"https://github.com/openshift/apiserver-library-go/commit/a994128188486d2dce99a528fbcc017d276081e0"},{"type":"WEB","url":"https://access.redhat.com/errata/RHSA-2023:3976"},{"type":"WEB","url":"https://access.redhat.com/errata/RHSA-2023:4093"},{"type":"WEB","url":"https://access.redhat.com/errata/RHSA-2023:4312"},{"type":"WEB","url":"https://access.redhat.com/errata/RHSA-2023:4898"},{"type":"WEB","url":"https://access.redhat.com/errata/RHSA-2023:5008"},{"type":"WEB","url":"https://access.redhat.com/security/cve/CVE-2023-1260"},{"type":"WEB","url":"https://bugzilla.redhat.com/show_bug.cgi?id=2176267"},{"type":"ADVISORY","url":"https://github.com/advisories/GHSA-92hx-3mh6-hc49"},{"type":"PACKAGE","url":"https://github.com/openshift/apiserver-library-go"},{"type":"WEB","url":"https://security.netapp.com/advisory/ntap-20231020-0010"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-05-04T09:00:06.750168469Z"}}
