The UI then automatically starts a login at the genuine identity provider but exchanges the returned authorization code together with its PKCE code_verifier at an attacker-controlled token endpoint. This lets the attacker\u00a0redeem the code for the victim&#8217;s access and refresh tokens. Alternatively, an attacker-controlled api_uri causes the UI to send the victim&#8217;s bearer token or Basic credentials to the attacker.
