Account Lock Bypass via Magic Link or Pass Key Authentication in WSO2 Identity Server Allows Unauthorized Access

Vulnerability Description

Due to a lack of user account state validation during authentication, locked user accounts can be successfully authenticated using Magic Link or Pass Key methods. This bypasses the intended security control that should prevent access to accounts that have been locked. This vulnerability may allow unauthorized access to applications and sensitive data associated with accounts that should have been restricted via the account lock mechanism. It also undermines the effectiveness of the account lock mechanism intended to prevent further login attempts.
