Executive Summary

This vulnerability is a server-side request forgery (SSRF) issue in the Azure MCP Server. It allows an authorized attacker to send crafted requests from the server, potentially accessing or manipulating internal resources that are not directly accessible to the attacker.

Through this SSRF vulnerability, the attacker can elevate their privileges over the network, gaining higher access rights than originally permitted.

Impact Analysis
