CVE-2026-58481 Network-AI vulnerability
Network-AI is a TypeScript/Node.js multi-agent orchestrator. Prior to version 5.12.2, `AgentRuntime` promises scoped file access under a configured sandbox `basePath`, but its path containment checks use raw string prefix tests. A sandbox base such as `/tmp/network-ai-sandbox` also matches a sibling path such as `/tmp/network-ai-sandbox_evil/secret.txt`. An agent/user that can call `AgentRuntime.readFile()` or `AgentRuntime.listDir()` can read or list files outside the intended sandbox when the target path is in a sibling directory sharing the base path prefix. This breaks the documented sandbox boundary. The issue is fixed in v5.12.2. `SandboxPolicy.resolvePath()` and `isPathAllowed()` now use separator-anchored prefix checks (`resolved === base || resolved.startsWith(base + path.sep)`) for both the allow-list and block-list. A sibling directory that merely shares a name prefix (e.g. `/srv/app-evil` vs base `/srv/app`) is no longer treated as in-scope.

Fixed versions
- Apply the latest vendor-supported patched version.
How to fix it
CVE-2026-58481 affects Network-AI and involves file access or path traversal. Successful exploitation may read, overwrite, or delete files outside the intended directory. Prioritize deployments that process untrusted input, expose the affected feature, or hold sensitive data. Upgrade Network-AI to 5.12.2 or a later vendor-supported fixed release.
- Inventory every deployment, device, package, plugin, container, build, and environment that uses Network-AI.
- Compare the installed version with the recorded affected range: < 5.12.2.
- Upgrade Network-AI to 5.12.2 or a later vendor-supported fixed release.
- Until patched, reject absolute and parent-relative paths, confine filesystem access to an explicit root, and accept files or manifests only from trusted sources.
- Review configuration, roles, tokens, network paths, and exposed endpoints connected to Network-AI; remove access that is not required.
- Review filesystem, application, and audit logs for parent-directory segments, absolute paths, unexpected reads, writes, or deletions outside the intended root.
- If exploitation is suspected, isolate affected assets, preserve evidence, rotate exposed credentials or keys, restore trusted data, and rebuild compromised systems before returning them to service.

Verify the fix
- Confirm every affected asset now runs the fixed vendor-supported release or has the documented mitigation for CVE-2026-58481 in place.
- Use a safe regression test to confirm the affected file access or path traversal path no longer produces the vulnerable behavior.
- Confirm temporary access controls, endpoint restrictions, network blocks, and least-privilege settings remain effective after the update.
- Review post-remediation logs and rerun Fixnx plus the relevant package, dependency, firmware, browser, or product-specific security check.
- Document affected assets, versions, changes, validation evidence, reviewed logs, and any credential rotation, cleanup, or replacement completed.
