AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N
Local write access to the environment data directory required (AV:L/PR:L); confidentiality-only impact as backup copies but never modifies or deletes external files.

Lifecycle Timeline
3DescriptionCVE.org
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.
AnalysisAI
Symlink traversal in Network-AI's EnvironmentManager.backup() allows a local attacker with write access to an environment data directory to exfiltrate arbitrary files from outside the environment root into readable backup artifacts. All Network-AI versions prior to 5.12.2 (npm package jovancoding/network-ai) are affected, confirmed in v5.12.1 per GHSA-6x2m-p4xp-wg22. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires local OS-level write access to the `data/<env>` directory of the target Network-AI environment - sufficient to create a symlink entry within it. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The NVD-assigned CVSS 3.1 score of 5.5 (Medium) with vector AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N is consistent with the described exploitation conditions: local filesystem write access is required (AV:L), complexity is low once access is obtained (AC:L), and only low-privilege local access is needed (PR:L). … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker with local write access to a shared Network-AI environment data directory - for example, in a multi-tenant deployment or a container where several users access `data/dev` - creates a symlink inside `data/dev` pointing to `/etc` or another sensitive external directory. The next time any backup operation runs (triggered manually via `network-ai env backup create --env dev` or automatically during a promote or restore), the backup recursion follows the symlink and copies external files into `data/dev/.backups/<backupId>/`. … |
| Remediation | Upgrade to Network-AI v5.12.2, available as a tagged GitHub release at https://github.com/Jovancoding/Network-AI/releases/tag/v5.12.2 and via npm. … Detailed patch versions, workarounds, and compensating controls in full report. |
