Fix
Public exploits 2
- HynekPetrak/log4shell-finder PoC on GitHub
- pimps/CVE-2017-5645 PoC on GitHub
Each line links to the index that lists it, never to exploit code. Exploit-DB's "verified" and a Metasploit rank of good or better count as verified; a PoC-in-GitHub entry is a repository's claim.
