Cross-Site Request Forgery (CSRF) is an attack in which an external site makes a request to another site on behalf of a user without consent. This attack often relies on an existing session on the target site, which the attacker hijacks for their own purposes. Various CSRF prevention and mitigation techniques exist such as the SameSite attribute, CSRF tokens and header validation.

Hotlinking refers to the practice of third-party web properties loading resources directly from your server. Unauthorised hotlinks are generally undesirable, not only because they can facilitate reproducing your content without permission. Web standards and browsers have come a long way in the last few decades, and they now include all of the tools needed for effective protection against hotlinking.
