We were noticed about the critical security bug in Total.js framework, but you are safe if you use a reverse proxy like NGINX or Apache. I'm very grateful for great analyse from security experts Riccardo Krauter, Dario Ragno, Fabio Cogno @ Certimeter Group. So thank you a lot!
The fix below is for all version of Total.js framework between v1.7 and v3.1 version. Just copy security.js file to definitions folder, for example: /your-app-dir/definitions/security.js.
/your-app/definitions/security.jsSorry for all troubles.
