CVE-2026-26118 is a server-side request forgery (SSRF) vulnerability in Azure MCP Server / Azure MCP Server Tools. The issue allows an authorized attacker to supply specially crafted input, including a malicious URL or user-controlled parameters to a server tool, causing the MCP server to make an outbound network request on the attacker’s behalf. According to the provided content, the outbound request may include the server’s managed identity token, enabling token capture. Because Azure MCP Server acts as a connector between AI agents and external tools, exploitation abuses the server’s trust and identity context rather than direct code execution. Microsoft describes the flaw as an elevation-of-privilege issue over the network.
