@nalvietnam/avatar-cli@3.39.0
AI harness CLI for NAL Vietnam engineering
AI Security Review
scanned 3d ago · by lpm-firewall-aiThe probe’s default destination is package-aligned, and it runs within an explicit diagnostic command. However, a custom telemetry URL can receive the saved ID token without a recipient restriction, so a credential exposure warning is warranted.
Static reason
One or more suspicious static signals were detected.
Trigger
Running the CLI diagnostic probe without `--no-probe` while `AVATAR_TELEMETRY_URL` points to a custom recipient.
Impact
A custom recipient can receive the saved token. The source does not establish exposure when the default NAL telemetry URL is used.
Mechanism
The probe reads the saved ID token and places it in the bearer authorization header of a POST request to the selected URL.
AI rationale
The probe’s default destination is package-aligned, and it runs within an explicit diagnostic command. However, a custom telemetry URL can receive the saved ID token without a recipient restriction, so a credential exposure warning is warranted.

Decision evidence
public snapshotAI called this Suspicious at 91.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- The diagnostic probe reads a saved ID token and accepts an environment-selected telemetry URL, defaulting to the NAL telemetry service.
- The probe sends that token as a bearer credential in a POST request; an overridden URL is not restricted to an approved host.
- The CLI exposes a `--no-probe` skip option, but the probe otherwise runs as part of its diagnostics.
- The bundle uses `.claude/avatar.json` and `.claude/avatar-po.json` as workspace markers; this is ordinary workspace detection.
- The postinstall hook only prints a welcome screen and exits under CI or when its skip flag is set.
Evidence against
- The probe’s default recipient is the package’s NAL telemetry service, and it sends a deliberately invalid probe payload.
- The credential exposure requires running the diagnostic with a custom telemetry URL; the postinstall hook does not perform the transfer.
