IEEE Spectrum: AI helped turn a PHP crash bug into PHP2Shell
IEEE Spectrum reports that researchers at Calif, using AI tools and sponsored by OpenAI, turned a 2024 PHP memory bug into the patched PHP2Shell remote-code flaw.
IEEE Spectrum reported this week that a critical PHP flaw dubbed PHP2Shell began as an out-of-memory crash filed with the PHP Foundation in 2024, then became remote-code execution after researchers used AI tools to map a precise memory-corruption path1.
The magazine said cybersecurity firm Calif, in an independent audit sponsored by OpenAI, found the conversion within two weeks, and that Wiz later confirmed and expanded the issues1. Sites that run PHP stacks such as WordPress and Drupal, including high-profile properties named in the piece, were described as in the blast radius until a patch shipped1.
Spectrum said the team reported the work to the PHP Foundation and that, as far as those sources knew, no malicious use of the exploit appeared before the fix1. Four engineers then spent about two months closing the hole without breaking existing behavior1.
Suman Jana of Columbia University told Spectrum that chaining the crash into control of a process is tedious reasoning that AI now handles well, while adding, “I’m not claiming that AI can do it all by itself. It clearly cannot”1. He said the tools mainly amplify experts and people just below that tier1.
Matt Suiche of Tolmo framed the episode as old human-written software being re-examined at scale, arguing that decades of technical debt are now due1. Jana pointed to an imbalance: finding bugs is getting cheaper while patches must seal every path and preserve function, a strain for underfunded open-source maintainers1.
He said frontier labs have donated model token budgets to hunt such bugs and cited Anthropic’s Oct. 22 formal-verification work, in which a model drafts a patch and a proof that a separate checker validates1. Johns Hopkins cryptographer Matthew Green was more skeptical, telling Spectrum that PHP2Shell was not severe enough in public impact to force a broader funding shift, and urging users to install security updates promptly1.
Jana said similar finds are likely, with the open question being whether researchers report them first1. Spectrum did not independently document in-the-wild exploitation, and Green’s 2027 timing for a more damaging incident was presented as his forecast, not a measured timeline1.
