- Mitigation guidance
- To mitigate this issue, configure the JDBC connection string for MySQL/MariaDB to explicitly set `useAffectedRows=true`. This ensures the database driver correctly reports affected rows, preventing the replay protection bypass. This mitigation is applicable only when Keycloak is deployed in stateless mode and utilizes MySQL or MariaDB as its database. A restart of the Keycloak service will be required for the configuration change to take effect.
