{"id":"CVE-2026-97847","published":"2026-11-05T18:17:11.840","lastModified":"2026-11-05T18:17:11.980","description":"A flaw was found in the protocol mapper and identity resolution components of Keycloak. The issue occurs when a client manager uses hardcoded-claim mappers to override identity claims in sessionless service-account tokens. Because these tokens lack a session ID, Keycloak may incorrectly resolve the token bearer as a different, highly privileged user based on the manipulated claims. This can allow an attacker with limited client management permissions to impersonate a realm administrator and gain full control over the realm.","cvssScore":7.1,"cvssSeverity":"HIGH","cvssVector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:L","cwes":["CWE-287"],"vendors":[],"products":[],"references":[{"url":"https://access.redhat.com/security/cve/CVE-2026-97847","tags":[]},{"url":"https://bugzilla.redhat.com/show_bug.cgi?id=2540950","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
