Résumé
MCP Go SDK Allows Cross-Site Tool Execution for HTTP Servers without Authorizatrion
Description d'origine
La description telle que publiée par la source (souvent en anglais).
The Go MCP SDK used Go's standard encoding/json. Prior to version 1.4.1, the Go SDK's Streamable HTTP transport accepted browser-generated cross-site POST requests without validating the Origin header and without requiring Content-Type: application/json. In deployments without Authorization, especially stateless or sessionless configurations, this allows an arbitrary website to send MCP requests to a local server and potentially trigger tool execution. Version 1.4.1 contains a patch for the issue.
