{"id":"CVE-2026-11986","aliases":[],"url":"https://o3.security/vulnerability/CVE-2026-11986","summary":"Keycloak Admin UI REST Extensions: bulk role-removal endpoints fail to perform granular permission checks","details":"A flaw was found in the admin-ui-ext component of Keycloak, which provides extended administrative user interface capabilities. The issue occurs because certain bulk role-removal endpoints fail to perform granular permission checks when deleting role mappings. This allows a delegated administrator with limited permissions to remove highly privileged roles from other users or groups, potentially disrupting administrative access control.","published":"2026-06-11T18:31:34Z","modified":"2026-08-19T19:45:08.151849149Z","cvss":{"score":4.9,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:N/I:H/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[{"ecosystem":"Maven","name":"org.keycloak:keycloak-rest-admin-ui-ext","fixedVersion":"26.7.0"}],"fix":{"url":"https://github.com/keycloak/keycloak/pull/49826","label":"keycloak/keycloak#49826"},"references":[{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-11986"},{"type":"WEB","url":"https://github.com/keycloak/keycloak/issues/49766"},{"type":"WEB","url":"https://github.com/keycloak/keycloak/pull/49826"},{"type":"WEB","url":"https://github.com/keycloak/keycloak/commit/f3831f01fd4abceb47e9675ab5f4c17268ba9e9d"},{"type":"WEB","url":"https://access.redhat.com/errata/RHSA-2026:50848"},{"type":"WEB","url":"https://access.redhat.com/errata/RHSA-2026:50849"},{"type":"WEB","url":"https://access.redhat.com/security/cve/CVE-2026-11986"},{"type":"WEB","url":"https://bugzilla.redhat.com/show_bug.cgi?id=2487906"},{"type":"PACKAGE","url":"https://github.com/keycloak/keycloak"},{"type":"WEB","url":"https://github.com/keycloak/keycloak/releases/tag/26.7.0"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-19T19:45:08.151849149Z"}}
