The authorization mechanism improperly truncates subresource names, leading to incorrect permission evaluations. This allows authenticated users with specific custom roles to gain unauthorized access to subresources, potentially disclosing sensitive information or performing actions they are not permitted to do. Additionally, legitimate users may be denied access to resources.","state":0,"publishedAt":null,"modifiedAt":null,"affected":[],"metrics":[{"system":"EUVD CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:N","score":5.4,"severity":null}],"references":["https://access.redhat.com/security/cve/CVE-2026-6383","https://bugzilla.redhat.com/show_bug.cgi?id=2458741"],"sourceUrl":"https://euvd.enisa.europa.eu/vulnerability/EUVD-2026-23009","license":"ENISA EUVD · source terms and attribution apply","enrichment":{"sourceStatus":null,"weaknesses":[],"productCriteria":[],"sourceDates":{"datePublished":"Apr 15, 2026, 6:22:30 PM","dateUpdated":"Apr 15, 2026, 6:40:31 PM"},"relatedAdvisories":[{"id":"msrc_CVE-2026-6383","title":"Kubevirt: kubevirt: unauthorized subresource access due to improper rbac evaluation","vulnerabilityIds":["CVE-2026-6383"]}],"note":"EUVD source date text has no stated timezone and is retained without inventing a UTC instant.
