Overview
utcp-http is an UTCP communication protocol plugin for HTTP, SSE, and streamable HTTP, plus an OpenAPI converter.
Affected versions of this package are vulnerable to Server-side Request Forgery (SSRF) via the call_tool process. An attacker can access internal network resources and exfiltrate sensitive data by registering a tool endpoint that issues a redirect to an internal service, causing the process to follow the redirect without revalidating the target. No special configuration is required for exploitation.
