Description
The WPCOM Member plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 1.7.27. The social login callback does not validate the OAuth state parameter and accepts the account-binding mode from a URL parameter. This makes it possible for unauthenticated attackers to bind a social account they control to a logged-in user's account and then log in as that user, granted they can trick the user into performing an action such as clicking a link. Exploitation requires social login to be enabled with at least one provider configured.
