{"id":"BIT-keycloak-2026-16106","summary":"Keycloak-services: keycloak-services: incorrect authorization in admin role-composite deletion allows delegated admin to remove privileged child roles","details":"A flaw was found in the admin REST API of Keycloak, a solution for identity and access management. The issue occurs when a delegated administrator attempts to remove a child role from a composite role. Due to missing authorization checks, an attacker with limited administrative permissions can remove privileged roles they are not authorized to manage, leading to a loss of access for other users and administrators.","aliases":["CVE-2026-16106"],"modified":"2026-09-17T14:45:08.856591736Z","published":"2026-08-31T14:37:02.882Z","database_specific":{"cpes":["cpe:2.3:a:redhat:build_of_keycloak:*:*:*:*:-:*:*:*","cpe:2.3:a:keycloak:keycloak:*:*:*:*:*:*:*:*"],"severity":"Medium"},"references":[{"type":"ADVISORY","url":"https://access.redhat.com/security/cve/CVE-2026-16106"},{"type":"ADVISORY","url":"https://bugzilla.redhat.com/show_bug.cgi?id=2501739"},{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-16106"},{"type":"WEB","url":"https://access.redhat.com/errata/RHSA-2026:68277"},{"type":"WEB","url":"https://access.redhat.com/errata/RHSA-2026:68278"}],"affected":[{"package":{"name":"keycloak","ecosystem":"Bitnami","purl":"pkg:bitnami/keycloak"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"26.7.3"}]}],"database_specific":{"source":"https://github.com/bitnami/vulndb/tree/main/data/keycloak/BIT-keycloak-2026-16106.json"},"severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:N/I:H/A:N"}]}],"schema_version":"1.9.0"}
