Description

HKUDS Vibe-Trading from 0.1.0 before 0.1.7 contains a missing authentication vulnerability that allows unauthenticated attackers to access the FastAPI surface because require_auth() returns early when API_AUTH_KEY is unset. Attackers can post messages to /sessions/{id}/messages to trigger root shell commands via BashTool, upload .py or .sh files via /upload, read session histories, and obtain partial API keys.
