CSRF Hacking Database
I'm not sure how I didn't stumble across this before but at least I did eventually find it. From the about page:
In the style of Johnny Longs googledorks, I bring you the CSRF Hacking Database.
This database will contain urls that exploit CSRF vulnerabilities in websites.
This is not intended to assist malicious hacking, rather it is intended to raise
awareness about CSRF vulnerabilities in general.
You can check out the database here.
