CVE-2026-42856 · Severity: high · CVSS 4 · Published 2026-05-11

Network-AI is a tool used for managing AI agents and orchestrating network tasks. A security flaw allows anyone with network access to the service to execute administrative commands without a password. This could allow an attacker to change system settings, create or delete security tokens, and interfere with active AI agents, potentially leading to unauthorized access or disruption of operations.

Technologies: Jovancoding Network-AI, network-ai (npm). Vendors: Jovancoding, npm.

Technical details

The Model Context Protocol (MCP) HTTP transport in Network-AI fails to implement authentication, session, or token checks in its `_handlePost()` and `handleRPC()` functions. By default, the server binds to `0.0.0.0`, making it reachable over the network. An unauthenticated attacker can send JSON-RPC `tools/call` requests to invoke privileged tools such as `config_set`, `agent_spawn`, and `token_create`. This allows for full enumeration and mutation of the orchestrator's live configuration, agent management, and security token lifecycle. The vulnerability is addressed in version 5.1.3.
