An unauthenticated remote attacker can exploit this by sending specially crafted SAML requests to the server, leading to high CPU utilization and a denial of service for all users.","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-107123"}],"crowd":[],"reference":{"nvd":{"published":"2026-11-05T17:17:34.950","score":7.5,"severity":"HIGH","desc":"A flaw was found in the SAML XML processing component of Keycloak, an open-source identity and access management solution.
