Claude Code flags fake "PHP2Shell" CVE from Wikipedia, refuses to patch a hoax

adulion · reddit · 2026-10-23

A user asked Claude Code to audit their PHP servers against a Wikipedia article, and Claude pushed back: the "PHP2Shell" incident is flagged as fictional/speculative (dated October 2026), with made-up CVE IDs (CVE-2026-109618/619) and a plot involving "OpenAI's Patch the Planet project."

Claude couldn't corroborate it in PHP security advisories, php.net release notes, or NVD, and explicitly refused to treat it as a patching reason—pointing to php.net/ChangeLog and NVD as authoritative sources. A notable anti-hallucination moment: the model verified sources instead of blindly trusting the citation.
