What are CSRF issues in Django and how can I prevent them?

CSRF stands for Cross-Site Request Forgery. It's a security vulnerability that allows an attacker to trick a user into submitting a request that they did not intend to make. In Django, this can happen if a user is authenticated and an attacker sends a request on their behalf without their consent.

How does Django protect against CSRF attacks?

Django provides built-in protection against CSRF attacks by using a CSRF token. This token is included in forms and must be submitted with any POST request. If the token is missing or incorrect, Django will reject the request.

What should I do if I encounter a CSRF verification failure?

If you encounter a CSRF verification failure, ensure that your form includes the CSRF token. You can add it in your templates using the {% csrf_token %} template tag. Also, check that your AJAX requests include the CSRF token in the headers.

Are there any exceptions to CSRF protection in Django?

Yes, you can exempt certain views from CSRF protection using the @csrf_exempt decorator. However, this should be done cautiously, as it can expose your application to CSRF attacks.
