Travelpayouts: All Travel Brands in One Place <= 1.1.16 - Open Redirect

The Travelpayouts: All Travel Brands in One Place plugin for WordPress is vulnerable to Open Redirect in versions 0.0.0.0 to 1.1.16. This is due to insufficient validation on the redirect url supplied via the travelpayouts_redirect parameter. This makes it possible for unauthenticated attackers to redirect users to potentially malicious sites if they can successfully trick them into performing an action.
