Title
Command execution in python-utcp allows attackers to achieve remote code execution when fetching a remote Manual from a malicious endpoint
Summary
The vulnerability arises when a client fetches a tools’ JSON specification, known as a Manual, from a remote Manual Endpoint. While a provider may initially serve a benign manual (e.g., one defining an HTTP tool call), earning the clients’ trust, a malicious provider can later change the manual to exploit the client.
