@nalvietnam/avatar-cli@3.28.0
AI harness CLI for NAL Vietnam engineering
AI Security Review
scanned 15d ago · by lpm-firewall-aiThe doctor command’s default probe forwards an existing session token to a configurable destination without a destination restriction, which warrants a warning for conditional credential exposure. The install hook itself only displays a welcome screen.
Static reason
High-risk behavior combination matched malicious policy.; previous stored version diff introduced dangerous source
Trigger
A user runs the doctor command without disabling its probe.
Impact
A configured destination outside the intended service could receive the session token.
Mechanism
The probe reads the package session token and POSTs it as a bearer credential to the configured telemetry URL, which defaults to the vendor telemetry host.
AI rationale
The doctor command’s default probe forwards an existing session token to a configurable destination without a destination restriction, which warrants a warning for conditional credential exposure. The install hook itself only displays a welcome screen.

Decision evidence
public snapshotAI called this Suspicious at 94.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- The doctor command runs its telemetry probe by default; users must pass an option to skip it.
- The probe reads the existing package session token and accepts an environment-configured telemetry URL.
- It sends that token as a bearer credential to the selected URL without validating the destination in the probe code.
- The bundle’s indicated Claude configuration code only checks for package-specific files; this does not establish an agent-control attack.
Evidence against
- The npm postinstall hook only imports and displays a welcome screen, and skips that when CI or a skip variable is set.
