CVE-2026-54051
No affected components available
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 tonetwork-ai@5.9.1or later. As defense in depth, avoid broad wildcard allowlist entries such asnode */npm *` which are direct code execution by design.
The vulnerability can be exploited over the network without needing physical access. It is easy for an attacker to exploit this vulnerability. An attacker needs basic access or low-level privileges. No user interaction is needed for the attacker to exploit this vulnerability. The vulnerability can affect other systems as well, not just the initial system. There is a high impact on the confidentiality of the information. There is a high impact on the integrity of the data. There is a high impact on the availability of the system.
Active exploitation in the wild has been confirmed. Immediate patching or mitigation is required.
The exploit probability is very low. The vulnerability is unlikely to be exploited in the next 30 days.
We did not find any exploit available. Neither in GitHub repositories nor in the Exploit-Database.
