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":"2026-04-15T19:16:38.52+00:00","modifiedAt":"2026-10-26T22:10:00.163+00:00","affected":[],"metrics":[{"system":"CVSS 3.1 · secalert@redhat.com · Secondary","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:N","score":5.4,"severity":"MEDIUM"}],"references":["https://access.redhat.com/security/cve/CVE-2026-6383","https://bugzilla.redhat.com/show_bug.cgi?id=2458741"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-6383","license":"NIST NVD usage terms; underlying source attribution retained","enrichment":{"sourceStatus":"Awaiting Analysis","weaknesses":["CWE-863"],"productCriteria":[],"sourceDates":{"published":"2026-04-15T19:16:38.520","lastModified":"2026-10-26T22:10:00.163"},"relatedAdvisories":[],"note":"NVD analysis and CPE criteria are source context, not proof that a package or your environment is affected.
