Factory Droid CLI - AI-powered software engineering agent
AI Security Review
scanned 1mo ago · by lpm-firewall-aiThe active installer contains a concrete, conditionally reachable credential-forwarding flaw. Static inspection found no fixed unrelated recipient or other evidence supporting a block.
Static reason
One or more suspicious static signals were detected.
Trigger
Package installation when the platform dependency is missing and an npm token is set.
Impact
A redirect or metadata-controlled lookalike hostname could receive the npm token.
Mechanism
The installer follows redirect-provided URLs and applies a substring-based hostname check before sending the token.
AI rationale
The active installer contains a concrete, conditionally reachable credential-forwarding flaw. Static inspection found no fixed unrelated recipient or other evidence supporting a block.

Decision evidence
public snapshotAI called this Suspicious at 90.0% confidence as Dangerous Capability with low false-positive risk.
Evidence for warning
- Package installation automatically runs the installer and declares platform binary dependencies.
- The installer sends the npm token whenever a requested hostname merely contains the npm registry string.
- The request helper follows redirect locations without enforcing an exact registry host.
- The download fallback runs when the platform dependency is unavailable.
Evidence against
- The token forwarding is conditional on both a missing platform dependency and an npm token being present.
- The initial metadata request targets the npm registry.

Install Time Lifecycle Scripts
Package defines install-time lifecycle scripts.
