Account security bug

Good evening. My password consists of numbers and one letter of the Latin alphabet, when entering the Blizzard services, the system does not distinguish the case of this letter, i.e. conventionally my password 123456789q is equal to the password 123456789Q. This is a gross security flaw that could compromise your account information

+1 Case is not considered on passwords.

Intentional always has been. Passwords are no longer case sensitive for Battle.net - #5 by Vrakthris - Customer Support - World of Warcraft Forums

Though this is also not the correct place to report, this is for bugs relating the Web API.
