Description
The patreon-connect plugin for WordPress is vulnerable to Open Redirect in all versions up to, and including, 1.9.17 due to insufficient validation of the 'final_redirect_uri' value in the request-supplied OAuth 'state' parameter in the OAuth callback handler. This makes it possible for unauthenticated attackers to redirect users to potentially malicious sites if they can successfully trick them into performing an action such as clicking on a link.
