CVE-2026-18770Public exploitNetwork attack vector

Unauthenticated Python code execution via /code

Published Aug 4, 2026 · Updated Aug 4, 2026

Code injection in VibeSurf at commit cd6e519d507cdd4d63061300bf60fb176e1f57e0 allows remote attackers to execute Python through /code. The public record identifies the /code Python validation handler but does not disclose the validation error that lets submitted code escape its intended restrictions. No authentication or user interaction is required; successful requests run attacker-supplied Python in the server process context.
