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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:H/UI:N/S:C/C:H/I:H/A:H","score":8.0},"cwes":["CWE-288"],"references":["https://access.redhat.com/errata/RHSA-2023:3976","https://access.redhat.com/errata/RHSA-2023:4093","https://access.redhat.com/errata/RHSA-2023:4312","https://access.redhat.com/errata/RHSA-2023:4898","https://access.redhat.com/errata/RHSA-2023:5008"],"products":["kubernetes:kube-apiserver","redhat:openshift_container_platform"],"source":"nvd","synced_at":"2026-10-19T21:39:34.467980132+00:00"},"epss":{"cve":"CVE-2023-1260","score":0.01556,"percentile":0.75181,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-92hx-3mh6-hc49","url":"https://osv.dev/vulnerability/GHSA-92hx-3mh6-hc49","summary":"kube-apiserver authentication bypass vulnerability","modified":"2026-05-04T09:00:06.750168469Z","packages":[{"ecosystem":"Go","name":"github.com/openshift/apiserver-library-go","purl":"pkg:golang/github.com/openshift/apiserver-library-go","ranges":["<0.0.0-20230621"],"fixed":["0.0.0-20230621"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
