OWASP Top 10 2007-2017: The Fall of CSRF. I was surprised to learn recently that CSRF didn’t make it into the 2017 OWASP Top 10 security vulnerabilities (after featuring almost every year since the list started). The credited reason is that web frameworks do a good enough job protecting against CSRF by default that it’s no longer a top-ten problem. Defaults really do matter.
