Since I have to go through a bunch of php repos today at work I ended up releasing a CLI tool that automates that process by listing out the steps you need to take to stay away from the vulnerability. Here's the link incase it helps anyone https://github.com/Amsozzer1/php2shell-repo-audit
Dude, today of all days is not when I'm going to trust some random CLI tool that was vibed out. I'm not saying your work isn't helpful, but it would probably be a lot better to just release your prompts you used to build this and let others build it on their own.
