CVE-2026-54051
CriticalCVSS 9.9Exploitation Probability (EPSS)
Low risk30th percentile - higher than 30% of all known CVEs
Summary
Vulnerability in Network-AI (TypeScript/Node.js) before version 5.9.1 allows bypassing the shell command allowlist. An attacker can execute arbitrary commands by injecting special characters (e.g., `;`).
Risk Assessment
Risk is high – an attacker could gain full control of the server by executing arbitrary system commands.
Recommendation
Update network-ai to version 5.9.1 or later. Avoid broad allowlist rules like `node *`.
Original NVD description (English source)
Network-AI is a TypeScript/Node.js multi-agent orchestrator. Prior to version 5.9.1, the agent sandbox gates shell commands behind an allowlist (`SandboxPolicy.isCommandAllowed`), which THREAT_MODEL.md calls the main control against a compromised agent (Adversary 3.2). The allowlist glob-matches the whole command string, but `ShellExecutor` runs that string through `/bin/sh -c`. So any wildcard allow such as `git *`, `npm *` or `node *` also matches `git status; <anything>`, and a scoped command becomes arbitrary execution. The issue is fixed in v5.9.1. `ShellExecutor` now executes via `spawn(file, args, { shell: false })` using a quote-aware parsed argv, so no shell is invoked. `SandboxPolicy.isCommandAllowed` and the new `SandboxPolicy.tokenizeCommand` reject any unquoted shell metacharacter (`; & | $ ` ` ` ( ) < > { }` newline) or unterminated quote before the allowlist glob match; quoted metacharacters are preserved as literal argument data. Users should upgrade to `[email protected]` or later. As defense in depth, avoid broad wildcard allowlist entries such as `node *` / `npm *` which are direct code execution by design.
