Description
The Welcart e-Commerce plugin for WordPress is vulnerable to Open Redirect via the 'usces_referer' parameter used after adding an item to the cart in all versions up to, and including, 2.12.5. This is due to insufficient validation of the redirect target host, and the 'Continue shopping' return URL taken from the HTTP referer was likewise not restricted to the site. This makes it possible for unauthenticated attackers to redirect users to potentially malicious sites if they can successfully trick them into performing an action.
