HCL AION is affected by a vulnerability where the account lockout mechanism did not sufficiently restrict repeated failed login attempts, allowing an attacker to make a large number of password guesses against a user account. This may increase the risk of account compromise through brute-force attacks, potentially resulting in unintended behavior or security impact under certain conditions.
