0 CVE-2026-108859 is a high-severity denial of service vulnerability in the mark3labs mcp-go library versions up to 1.2.1. It occurs in the StreamableHTTPServer.ServeHTTP function, where remote unauthenticated attackers can exhaust server memory by sending oversized POST requests. The server reads the entire POST body via io.ReadAll before validating it, allowing attackers to send arbitrarily large or many concurrent POST requests to degrade or crash the server process.
