Network-AI: Improper Neutralization of Special Elements used in an OS Command

CVE-2026-54051GHSA-qw6v-5fcf-5666

What to do

Vendor fix available. Upgrade each affected package to the fixed version on its release line (network-ai 5.9.1), redeploy, then verify what is actually installed.

This page has no inventory attached, so it cannot say whether you are affected. A vendor fix is not proof that your deployment is fixed.

Source description

As published by the source; long descriptions are shortened.

Summary The agent sandbox gates shell commands behind an allowlist (SandboxPolicy.isCommandAllowed), which THREATMODEL.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. Root cause Matching and execution disagree on what a command is. Lines pinned to 40e42d7 (lib/agent-runtime.ts is identical to the v5.8.5 tag). 1. isCommandAllowed matches the full string, with no tokenizing and no metacharacter check: https://github.com/Jovancoding/Network-AI/blob/40e42d7a0a966b948953b3c524cf15355d20ef5e/lib/agent-runtime.ts#L248-L260 2. globMatch compiles to . and anchors it, so git becomes ^git .$ and matches git status; id:…

# Patch Next advisory brief: CVE-2026-54051

Advisory: Network-AI: Improper Neutralization of Special Elements used in an OS Command
IDs: CVE-2026-54051, GHSA-qw6v-5fcf-5666
Record: https://patchnext.com/advisories/cve-2026-54051 (revision 3, source checked 26 Oct 2026, 12:56 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Critical (CVSS 9.9)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: network-ai 5.9.1. A vendor fix does not mean a deployment is fixed.

## Affected components
- npm network-ai: affected < 5.9.1; fixed in 5.9.1

## Suggested inspection (read-only)
- `npm ls network-ai --all`: lists every installed copy and version, including transitive ones. Run in the project root after `npm ci`.

## Supported action
Upgrade each affected component to a fixed version on its release line. For a transitive dependency, upgrade the parent package or add an override or constraint, then regenerate the lockfile. Redeploy every environment that ran an affected version.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on network-ai.
- Repeat the inspection and confirm that only fixed versions remain installed.

## Rollback considerations
- Keep the previous lockfile and deployment artifact. Rolling back reinstates the vulnerable version, so apply any documented mitigation while you fix forward.

## Unresolved questions
- Which deployments run an affected version?
- Exploitation status can change. Check again before lowering the priority.
- Mark the work resolved only after the fixed version is verified in production.

## Sources
- Verified: https://github.com/advisories/GHSA-qw6v-5fcf-5666 (GitHub-reviewed advisory GHSA-qw6v-5fcf-5666 lists affected ranges: npm network-ai >=0 <5.9.1)
- Verified: https://osv.dev/vulnerability/GHSA-qw6v-5fcf-5666 (OSV record GHSA-qw6v-5fcf-5666 lists affected ranges: npm network-ai >=0 <5.9.1 (fixed))
