Keycloak Services has a potential bypass of brute force protection
If an attacker launches many login attempts in parallel then the attacker can have more guesses at a password than the brute force protection configuration permits. This is due to the brute force check occurring before the brute force protector has locked the user. **Acknowledgements:** Special thanks to Maurizio Agazzini for reporting this issue and helping us improve our project.
