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 tokenUrl field in OAuth2 security schemes during OpenAPI conversion. An attacker can cause sensitive credentials to be sent to an arbitrary endpoint by supplying a malicious OpenAPI specification containing a crafted tokenUrl, which is not validated before use. This enables exfiltration of OAuth2 client credentials or the ability to direct POST requests to internal network services.
