CVE-2026-90997 Keycloak-services: keycloak: replay protection bypass leads to unauthorized access via database driver semantics mismatch

A flaw was found in Keycloak. When deployed in stateless mode with MySQL or MariaDB, a mismatch in row-count semantics between the database driver and Keycloak's application logic allows an attacker to bypass replay protection. This vulnerability enables an attacker who intercepts single-use...
