The issue occurs because the system does not properly restrict which claim names can be used when setting up new clients. An attacker with valid registration credentials could create a client that incorrectly maps standard user profile information to sensitive security roles, potentially allowing them to gain unauthorized privileges on external applications that trust Keycloak tokens."], "mitigation": {"lang": "en:us", "value": "Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base, or stability."}, "name": "CVE-2026-96547", "package_state": [{"cpe": "cpe:/a:redhat:build_keycloak:", "fix_state": "Affected", "package_name": "keycloak-services", "product_name": "Red Hat Build of Keycloak"}, {"cpe": "cpe:/a:redhat:build_keycloak:", "fix_state": "Affected", "package_name": "rhbk/keycloak-rhel9", "product_name": "Red Hat Build of Keycloak"}, {"cpe": "cpe:/a:redhat:red_hat_single_sign_on:7", "fix_state": "Not affected", "package_name": "keycloak-services", "product_name": "Red Hat Single Sign-On 7"}], "public_date": "2026-11-05T00:00:00Z", "references": ["https://www.cve.org/CVERecord?id=CVE-2026-96547\nhttps://nvd.nist.gov/vuln/detail/CVE-2026-96547"], "statement": "The Red Hat Product Security team has assessed the severity of this vulnerability as Moderate, given that exploitation requires a valid Initial Access Token and only impacts external relying parties that rely on token claims for authorization. Successful exploitation allows an attacker to forge realm roles in tokens issued to these parties, potentially leading to privilege escalation. The vulnerability's root cause is a lack of claim name restriction during the Dynamic Client Registration process.", "threat_severity": "Moderate"}
