{"id":"CVE-2026-54051","state":"PUBLISHED","title":"Network-AI has an an OS Command Injection issue","description":"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 `network-ai@5.9.1` or later. As defense in depth, avoid broad wildcard allowlist entries such as `node *` / `npm *` which are direct code execution by design.","publishedAt":"2026-07-20T16:24:20.791Z","updatedAt":"2026-07-21T16:03:01.029Z","severity":{"score":9.9,"label":"Critical","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H","source":"GitHub_M"},"assigner":"GitHub_M","products":["Jovancoding Network-AI"],"affected":[{"vendor":"Jovancoding","product":"Network-AI","versions":[{"version":"< 5.9.1","status":"affected"}]}],"references":["https://github.com/Jovancoding/Network-AI/security/advisories/GHSA-qw6v-5fcf-5666","https://github.com/Jovancoding/Network-AI/commit/379f77656b578144e03415c5b134d8309a4b5792"],"weaknesses":["CWE-78"],"ingestedAt":"2026-10-29T20:12:24.861Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/54xxx/CVE-2026-54051.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-54051","state":"PUBLISHED","datePublished":"2026-07-20T16:24:20.791Z","dateUpdated":"2026-07-21T16:03:01.029Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2026-06-11T18:24:35.096Z"},"containers":{"cna":{"title":"Network-AI has an an OS Command Injection issue","descriptions":[{"lang":"en","value":"Network-AI is a TypeScript/Node.js multi-agent orchestrator.
