fetch-mcp v1.0.2 and before is vulnerable to Server-Side Request Forgery (SSRF) vulnerability, which allows attackers to bypass private IP validation and access internal network resources.
Weakness
The web server receives a URL or similar request from an upstream component and retrieves the contents of this URL, but it does not sufficiently ensure that the request is being sent to the expected destination.
