CVE-2026-46701 · Severity: high · CVSS 7.6 · Published 2026-07-20

Network-AI is a tool used to manage and coordinate multiple AI agents. A security flaw in its server component allows unauthorized individuals to remotely control the software if it is running on a user's computer. By tricking a user into visiting a malicious website, an attacker can silently execute commands to change configurations, spawn new AI agents, or modify internal data without needing any passwords or credentials.

Technologies: [Jovancoding Network-AI](https://junglewise.ai/threats/technologies/network-ai), [network-ai (npm)](https://junglewise.ai/threats/technologies/npm-network-ai). Vendors: [Jovancoding](https://junglewise.ai/threats/vendors/jovancoding), [npm](https://junglewise.ai/threats/vendors/npm).

**Which products and versions are affected?** Jovancoding Network-AI < 5.4.5, <= 5.4.4; network-ai (npm) SEMVER:introduced=0,fixed=5.4.5.

**Is there a fix for CVE-2026-46701?** Yes. network-ai (npm): upgrade to 5.4.5 or later. Junglewise finds every place you run it, drafts the upgrade and applies it once you approve.

**How is CVE-2026-46701 attacked?** It is attacked over the network, in a software library.

**Am I affected by CVE-2026-46701?** Check whether you run Jovancoding Network-AI or network-ai (npm) at an affected version. Junglewise does that check for you around the clock: connect your code, cloud and domains, and it matches new vulnerabilities like this one against what you actually run and tells you when one reaches you.

## How to fix

- network-ai (npm): upgrade to 5.4.5 or later

  ```sh
  npm install network-ai@5.4.5
  ```


## Technical details

The Network-AI MCP SSE server defaults to an empty secret for authentication, causing the `_isAuthorized` check to return true for all requests even when no Authorization header is present. Simultaneously, the server implements a wildcard 'Access-Control-Allow-Origin: *' header on all responses. This combination allows an unauthenticated attacker to perform a Cross-Origin Resource Sharing (CORS) exploit. If a user running the server locally visits a malicious webpage, that page can use browser-based fetch requests to invoke any of the 22 exposed MCP tools (such as `config_set` or `agent_spawn`) and read the results. The issue is fixed in version 5.4.5 by requiring a non-empty secret and restricting CORS origins to localhost.
