What is CVE-2026-48814?

Network-AI versions 5.7.1 and earlier present a significant security flaw where the MCP SSE server allows unauthenticated invocation of various MCP tools due to a lack of a default secret. Despite previous fixes addressing related CORS issues, the server continued to operate without proper authentication, enabling unauthorized non-browser entities to access critical functions without credentials. This vulnerability was resolved in version 5.7.2.

Affected Version(s)

Network-AI < 5.7.2
