This includes the case where the user has previously approved an authorization request for a given client id But Doorkeeper automatically processes authorization requests without user consent for public clients that have been previously approved. Public clients are inherently vulnerable to impersonation, their identity cannot be assured.

VCID-vfr9-mu8k-rbg5 Aliases: CVE-2018-1000088 GHSA-hwhh-2fwm-cfgw	XSS on authorization consent view Stored XSS on the OAuth Client's name will cause users being prompted for consent via the `implicit` grant type to execute the XSS payload. The XSS attack could gain access to the user's active session, resulting in account compromise. Any user is susceptible if they click the authorization link for the malicious OAuth client. Because of how the links work, a user cannot tell if a link is malicious or not without first visiting the page with the XSS payload. In addition, there is stored XSS in the `native_redirect_uri` form element.	4.2.6 Affected by 2 other vulnerabilities.
