Description

Active access tokens are not revoked or invalidated when a user account is locked within WSO2 Identity Server. This failure to enforce revocation allows previously issued, valid tokens to remain usable, enabling continued access to protected resources by locked user accounts. The security consequence is that a locked user account can maintain access to protected resources through the use of existing, unexpired access tokens. This creates a security gap where access control policies are bypassed, potentially leading to unauthorized data access or actions until the tokens naturally expire.
