signull on AI-found PHP exploits: economic liability is the forcing function legacy software needs

signulll · x · 2026-10-23

signulll reflects on the recent wave of AI-discovered PHP vulnerabilities: it's striking how much critical infrastructure still runs on PHP, a stack he remembers as a kid's tool from building PHP+MySQL sites with 50k+ monthly uniques and hacking vBulletin.

His contrarian take: finding these exploits early with advanced AI is a good thing — economic liabilities are an excellent forcing function for legacy institutions to address technical debt, and they should be using sophisticated AI to secure their systems anyway. Real costs to ordinary users suck, but "everything is a trade off."
