AI Security Review
scanned 13d ago · by lpm-firewall-aiThe user-invoked doctor probe sends an existing service token to an unrestricted configurable endpoint, creating a concrete conditional credential exposure. The package postinstall only displays a welcome screen, so the evidence supports a warning rather than a publish block.
Static reason
One or more suspicious static signals were detected.
Trigger
A user invokes `avatar doctor` without `--no-probe`.
Impact
The configured endpoint receives the existing session token and may be able to use it as a credential.
Mechanism
The probe reads the token and sends it in an HTTP authorization header to the URL from `AVATAR_TELEMETRY_URL`, which is not restricted to approved hosts.
AI rationale
The user-invoked doctor probe sends an existing service token to an unrestricted configurable endpoint, creating a concrete conditional credential exposure. The package postinstall only displays a welcome screen, so the evidence supports a warning rather than a publish block.

Decision evidence
public snapshotAI called this Suspicious at 96.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- The `doctor` command runs the telemetry probe by default; `--no-probe` disables it.
- The probe reads an existing ID token and sends it as a bearer credential to a configurable URL without a destination allowlist.
- The package’s postinstall only loads a welcome screen; the credential exposure requires invoking `doctor`.
Evidence against
- The probe uses a fixed telemetry host by default, and the user can disable it with `--no-probe`.
- The auth endpoint separately enforces HTTPS and limits destinations to specified hosts.
