Overview
Affected versions of this package are vulnerable to Open Redirect in OAuth2AuthorizationCodeRequestAuthenticationConverter, OAuth2AuthorizationCodeRequestAuthenticationProvider, and OAuth2AuthorizationCodeRequestAuthenticationValidator. An attacker can redirect a victim to an attacker-controlled site by sending an authorization request with an invalid request_uri paired with an unvalidated redirect_uri. When the authorization endpoint processes that request, it can accept the attacker-supplied redirect target instead of suppressing the redirect on the validation failure, sending the user-agent to the malicious destination.
