{"id":"CVE-2026-2733","aliases":[],"url":"https://o3.security/vulnerability/CVE-2026-2733","summary":"Keycloak: Missing Check on Disabled Client for Docker Registry Protocol","details":"A flaw was identified in the Docker v2 authentication endpoint of Keycloak, where tokens continue to be issued even after a Docker registry client has been administratively disabled. 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":"2026-02-19T18:31:51Z","modified":"2026-09-10T03:50:34.968469909Z","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":[{"ecosystem":"Maven","name":"org.keycloak:keycloak-services","fixedVersion":null}],"fix":{"url":"https://github.com/keycloak/keycloak/commit/743ac24081b2c6da36aac3775147ec5b80c2861e","label":"keycloak/keycloak@743ac24"},"references":[{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-2733"},{"type":"WEB","url":"https://github.com/keycloak/keycloak/issues/46462"},{"type":"WEB","url":"https://github.com/keycloak/keycloak/commit/743ac24081b2c6da36aac3775147ec5b80c2861e"},{"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"},{"type":"PACKAGE","url":"https://github.com/keycloak/keycloak"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-09-10T03:50:34.968469909Z"}}
