Besides the problem of people being able to do this themselves, there's the problem of people who develop and sell, or sometimes give away, exploits. The people scrambling to publish POCs without verifying that they're demonstrating the right vulnerabilities are unintentionally helping out by making it difficult to find how to exploit the real vulnerabilities. Like what are you supposed to search for "php2shell exploit for real not fake?" You almost need an AI agent in a sandbox to download and run all the POCs to weed out the fake ones until one of them becomes well known.
