EchelonGraph scoreMEDIUM confidence

This critical-severity CVE scores 9.9 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 0.7%, top 50% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

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; , 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.
