This means that turning the client “Enabled” setting to OFF does not fully prevent access. As a result, previously valid credentials can still be used to obtain authentication tokens. This weakens administrative controls and could allow unintended access to container registry resources.","published":"2026-02-19T08:16:17.980","modified":"2026-06-17T10:31:37.293","cvss":{"score":3.8,"severity":"LOW","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:L/I:L/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[],"fix":null,"references":[{"type":"WEB","url":"https://access.redhat.com/errata/RHSA-2026:3947"},{"type":"WEB","url":"https://access.redhat.com/errata/RHSA-2026:3948"},{"type":"WEB","url":"https://access.redhat.com/security/cve/CVE-2026-2733"},{"type":"WEB","url":"https://bugzilla.redhat.com/show_bug.cgi?id=2440895"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-06-17T10:31:37.293"}}
