Threats affecting pkg:github/org.keycloak:keycloak-services

A concurrency flaw in Keycloak's login-failure storage component affects multi-node deployments using MySQL or MariaDB. Simultaneous failed login attempts for the same user can cause a synchronization error that locks the user's database record, blocking legitimate login attempts and causing failures. Additionally, some failed attempts may not be recorded properly, potentially bypassing brute-force protection.
