Technical details
OAuth access tokens remain valid for their full lifetime even after the OAuth client application they are bound to is disabled. This is a logic flaw in token lifecycle management where token revocation is not triggered by client deactivation. An attacker with a valid access token can bypass application-level access controls to continue API operations after the legitimate application has been removed.
