The issue occurs in the group-membership endpoints where the system fails to check if a group grants administrative privileges before allowing a user to be added. This allows a delegated administrator with limited permissions to add themselves to a high-privilege group, potentially gaining full control over the entire realm.","cvssScore":6.6,"cvssSeverity":"MEDIUM","cvssVector":"CVSS:3.1/AV:N/AC:H/PR:H/UI:N/S:U/C:H/I:H/A:H","cwes":["CWE-862"],"vendors":[],"products":[],"references":[{"url":"https://access.redhat.com/security/cve/CVE-2026-94000","tags":[]},{"url":"https://bugzilla.redhat.com/show_bug.cgi?id=2537168","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
