The record
The AGUI endpoint (`POST /agui`) has no authentication and hardcodes `Access-Control-Allow-Origin: *` on all responses. Combined with Starlette/FastAPI's Content-Type-agnostic JSON parsing, any website a victim visits can silently trigger arbitrary agent execution against a locally-running AGUI server and read the full response, including tool execution results and potentially sensitive data from the victim's environment.
