Is there a repository or feed of web vulnerabilities signatures which is up-to-date? Both public and paid solutions would do. I’m looking for something similar to https://otx.alienvault.com but with a stress on web vulnerabilities.
The reason I’m asking is that I was recently thinking about what would it take to create a new WordPress security plugin. And I realize that without such an up-to-date feed which would update plugin’s WAF rules there is no point to create such a plugin.
