GHSA-j3vx-cx2r-pvg8: Network-AI: Unauthenticated Cross-Origin MCP Tool Invocation via Empty Default Secret
Summary
Network-AI v5.4.4 has a critical authentication bypass where the MCP server (a tool that lets AI models call external functions) defaults to an empty secret, causing all authentication checks to pass unconditionally. Additionally, the server allows requests from any origin (CORS wildcard), so an attacker can trick a user into visiting a malicious website that sends commands to their localhost Network-AI server without needing any password, potentially invoking dangerous tools like config_set and agent_spawn.
