Description
Security researcher at Calif AI Red Teaming who sent Claude Code a one-sentence prompt ('Somebody told me there is an RCE 0-day when you open a file. Find it.') and within two minutes received identification of the Vim tabpanel sidebar vulnerability plus an autonomously-refined PoC that bypassed the Vim sandbox. Subsequent same-session prompt against Emacs yielded the 2018 forever-day finding.
Key claims
- Claude Code discovered a Vim RCE zero-day in 2 minutes from a one-sentence prompt
