Input validation vulnerability in Travelpayouts: All Travel Brands in One Place 1.1.16

The Travelpayouts plugin for WordPress, which combines all travel brands in one place, has a security vulnerability in versions 0.0.0.0 to 1.1.16. This is because the plugin does not properly check the redirect url provided through the travelpayouts_redirect parameter. This means that someone without authorization could redirect users to harmful websites if they can deceive them into doing something.
