An attacker with specific permissions on the hub cluster, and knowledge of a prior credential value, could exploit an authorization bypass vulnerability. By manipulating `copiedFrom` labels, the attacker could intercept newly rotated provider credentials, leading to unauthorized information disclosure. This allows access to sensitive credentials that should otherwise be protected.","published":"2026-08-12T21:17:38.000Z","lastModified":"2026-10-23T19:10:00.000Z","status":"Awaiting Analysis","sourceIdentifier":"secalert@redhat.com","cvss":{"version":"3.1","score":5.8,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:R/S:C/C:H/I:N/A:N"},"cwe":["CWE-639"],"affected":[],"epss":{"score":0.00399,"percentile":0.34022,"date":"2026-10-27","history":[]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"low","text":"Lower severity and a low EPSS score (0.40%).
