{"id":"GHSA-6w3v-mcfh-m3q7","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.","aliases":["BIT-keycloak-2026-11986","CVE-2026-11986"],"modified":"2026-08-26T01:11:56.045098327Z","published":"2026-06-11T18:31:34Z","database_specific":{"severity":"MODERATE","github_reviewed":true,"github_reviewed_at":"2026-08-19T19:32:02Z","nvd_published_at":"2026-06-11T18:16:25Z","cwe_ids":["CWE-425"]},"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"}],"affected":[{"package":{"name":"org.keycloak:keycloak-rest-admin-ui-ext","ecosystem":"Maven","purl":"pkg:maven/org.keycloak/keycloak-rest-admin-ui-ext"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"26.7.0"}]}],"versions":["21.0.0","21.0.1","21.0.2","21.1.0","21.1.1","21.1.2","22.0.0","22.0.1","22.0.2","22.0.3","22.0.4","22.0.5","23.0.0","23.0.1","23.0.2","23.0.3","23.0.4","23.0.5","23.0.6","23.0.7","24.0.0","24.0.1","24.0.2","24.0.3","24.0.4","24.0.5","25.0.0","25.0.1","25.0.2","25.0.3","25.0.4","25.0.5","25.0.6","26.0.0","26.0.1","26.0.2","26.0.3","26.0.4","26.0.5","26.0.6","26.0.7","26.0.8","26.1.0","26.1.1","26.1.2","26.1.3","26.1.4","26.1.5","26.2.0","26.2.1","26.2.2","26.2.3","26.2.4","26.2.5","26.3.0","26.3.1","26.3.2","26.3.3","26.3.4","26.3.5","26.4.0","26.4.1","26.4.2","26.4.3","26.4.4","26.4.5","26.4.6","26.4.7","26.5.0","26.5.1","26.5.2","26.5.3","26.5.4","26.5.5","26.5.6","26.5.7","26.6.0","26.6.1","26.6.2","26.6.3","26.6.4"],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/06/GHSA-6w3v-mcfh-m3q7/GHSA-6w3v-mcfh-m3q7.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:N/I:H/A:N"}]}
