Name of the Vulnerable Software and Affected Versions utcp-http versions prior to 1.1.4

Description The library fails to validate the tokenUrl field within remote OpenAPI specifications. This allows an attacker to redirect the submission of credentials to arbitrary endpoints. If a user registers an attacker-controlled OpenAPI specification and invokes a generated OAuth2-protected tool, the library sends the client id and client secret via a POST request to the attacker-supplied token endpoint.

Recommendations Update to version 1.1.4 or later.
