Description
@utcp/http versions before 1.1.14 have a server-side request forgery (SSRF) vulnerability that allows attackers to bypass remote-loopback checks using a {host} placeholder. This enables remote attackers to access internal loopback services such as 127.0.0.1 on the affected agent machine by supplying crafted host arguments or registering tools via Streamable HTTP and SSE discovery.
