{"id":"GHSA-92hx-3mh6-hc49","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.","aliases":["CVE-2023-1260"],"modified":"2026-05-04T09:00:06.750168469Z","published":"2023-09-24T03:30:20Z","database_specific":{"github_reviewed":true,"github_reviewed_at":"2023-09-25T18:32:19Z","nvd_published_at":"2023-09-24T01:15:42Z","cwe_ids":["CWE-288"],"severity":"HIGH"},"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"}],"affected":[{"package":{"name":"github.com/openshift/apiserver-library-go","ecosystem":"Go","purl":"pkg:golang/github.com/openshift/apiserver-library-go"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"0.0.0-20230621"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2023/09/GHSA-92hx-3mh6-hc49/GHSA-92hx-3mh6-hc49.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:H/UI:N/S:C/C:H/I:H/A:H"}]}
