CVE-2025-10097Public exploitNetwork attack vector

Unauthenticated remote code execution via VM escape

Published Sep 8, 2025 · Updated Sep 9, 2025

Code injection in SimStudioAI Sim 1.0 allows remote attackers to execute arbitrary server-side JavaScript through the function API. The POST handler interpolates the request's code value into a Node.js VM Script and runs it in a context that an attacker can escape through a constructor chain. The exposed route requires no authentication, and escaped code can load child_process and execute commands with the application container's privileges.
