Alongside the PHP2Shell disclosure, OpenAI announced Patch the Planet, a framework for coordinating AI-found vulnerability disclosures with vendors and governments, and said it would spend $1 billion subsidizing access to its Daybreak security auditing platform for under-resourced organizations. Greg Brockman said OpenAI led a two-month coalition on the PHP fix.
What to do: Program live; outside reviewers invited.
AI angle: Found with GPT-5.6 Sol; the UK government said NCSC was briefed by OpenAI a week before disclosure.
OpenAI models helped researchers, operating as part of our Patch the Planet initiative, discover critical security flaws in PHP, an open-source programming language used to run an estimated 70% of websites. Due to the severity of these flaws and PHP’s widespread use, we consider this bug to be one of the most impactful
Why this score
A defensive program announcement; relevant because it confirms AI models are now a primary source of critical vulnerability discoveries.
