Weakness: CWE-613

Description

admin3 through 3.0.0 fails to invalidate existing sessions when disabling a user account, allowing attackers to retain authenticated access with original permissions. Attackers can continue using bearer tokens issued before account disablement to authenticate requests, as the AuthInterceptor never re-validates the user's locked status and session expiry resets on each request.
