Description

One the leading vulnerabilities in current web application is Template Injeciton. For example When u are using aa javascript library like Angularjs, You should be careful that data reflected from user (from search box for example) will not be rendered in the context that there is another template handler (like angularjs) which will lead to Template Injection.

for example user sends [[test]] via search box of django. this will of course will not create any vulnerability for django, but if this value is rendered in template and there is angularjs, it will give attacker to do some Client-side Attacks.
