Critical vulnerabilities found in the PHP programming language, discovered with the help of AI tools from OpenAI and Google's Wiz, caused major outages on Wednesday at sites including 4chan, DeviantArt and Wikipedia, and prompted some Dutch and Finnish government agencies to take sites offline as a precaution.

TechCrunch reported the flaws compounded a broader rough week for internet security, which also saw newly disclosed vulnerabilities in Node.js and the popular AI tool LiteLLM.
