Description
Mattermost versions 10.1.x <= 10.1.2, 10.0.x <= 10.0.2, 9.11.x <= 9.11.4, and 9.5.x <= 9.5.12 fail to prevent concurrently checking and updating the failed login attempts. which allows an attacker to bypass of "Max failed attempts" restriction and send a big number of login attempts before being blocked via simultaneously sending multiple login requests
