@nalvietnam/avatar-cli@3.32.0
AI harness CLI for NAL Vietnam engineering
AI Security Review
scanned 15d ago · by lpm-firewall-aiThe doctor probe forwards an existing service token to an unrestricted environment-configured endpoint, so it presents conditional credential exposure despite requiring an explicit doctor command. 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 `avatar doctor`; the probe runs unless `--no-probe` is supplied.
Impact
A configured unrelated endpoint can receive the user's login token.
Mechanism
The probe reads a token using the package token reader, selects `AVATAR_TELEMETRY_URL` when set, and sends the token in an Authorization header without restricting the destination.
AI rationale
The doctor probe forwards an existing service token to an unrestricted environment-configured endpoint, so it presents conditional credential exposure despite requiring an explicit doctor command. The install hook itself only displays a welcome screen.

Decision evidence
public snapshotAI called this Suspicious at 95.0% confidence as Dangerous Capability with low false-positive risk.
Evidence for warning
- `dist/index.js` reads an existing login token through the package token reader.
- The doctor command runs the telemetry probe by default; `--no-probe` disables it.
- The probe accepts `AVATAR_TELEMETRY_URL` without a destination allowlist and sends the token as a Bearer credential.
Evidence against
- The postinstall hook only displays a welcome screen and skips it in CI or when requested.
