python-utcp before 1.1.4 SSRF via unvalidated HTTP redirects
Publisher and source text is retained separately from QFinch interpretation.
QFinch assessment
python-utcp versions before 1.1.4 contain a server-side request forgery vulnerability in HttpCommunicationProtocol.call_tool that validates the initial tool URL but follows HTTP redirects without re-validating the target. Attackers controlling a tool endpoint can return a 302 redirect to internal services, allowing the UTCP client to reach cloud metadata endpoints or internal HTTP services and return their response bodies to the caller.
