The OnAir2 WordPress theme before 3.9.9.2 and QT KenthaRadio WordPress plugin before 2.0.2 have exposed proxy functionality to unauthenticated users, sending requests to this proxy functionality will have the web server fetch and display the content from any URI, this would allow for SSRF (Server Side Request Forgery) and RFI (Remote File Inclusion) vulnerabilities on the website.
