{"id":"CVE-2026-11986","aliases":["GHSA-6w3v-mcfh-m3q7"],"url":"https://o3.security/vulnerability/CVE-2026-11986","summary":"Keycloak-rest-admin-ui-ext: authorization bypass vulnerability in the admin-ui-ext bulk role-mapping-delete endpoints of keycloak","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":"2026-08-25T11:41:32.393Z","modified":"2026-09-08T08:48:06.606933487Z","cvss":null,"epss":{"score":0.00301,"percentile":0.22826,"asOf":"2026-09-17"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Bitnami","name":"keycloak","fixedVersion":"26.6.5"}],"fix":null,"references":[{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2026:50848"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2026:50849"},{"type":"ADVISORY","url":"https://access.redhat.com/security/cve/CVE-2026-11986"},{"type":"ADVISORY","url":"https://bugzilla.redhat.com/show_bug.cgi?id=2487906"},{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-11986"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-09-08T08:48:06.606933487Z"}}
