AI Security Review
scanned 26d ago · by lpm-firewall-aiSource inspection found an automatic postinstall telemetry request, but it requires a previously recorded positive consent setting and sends limited installation metadata. The updater contacts the npm registry for this package's version; no concrete attack behavior was established.
Static reason
One or more suspicious static signals were detected.; previous stored version diff introduced dangerous source
Trigger
Package installation triggers postinstall; sending additionally requires existing telemetry consent and no opt-out or CI guard.
Impact
A consenting installation reports package version and coarse runtime details; no confirmed attack effect was established.
Mechanism
The script posts an anonymous install event to the configured telemetry host and exits on errors or timeout.
AI rationale
Source inspection found an automatic postinstall telemetry request, but it requires a previously recorded positive consent setting and sends limited installation metadata. The updater contacts the npm registry for this package's version; no concrete attack behavior was established.

Decision evidence
public snapshotAI called this Clean at 91.0% confidence as Benign with low false-positive risk.
Evidence for AI clean decision
- package.json runs scripts/postinstall.cjs automatically after installation.
- The postinstall exits unless the existing config records telemetry consent as true.
- With consent, the install script sends an install event to a host configurable through EXTENSHI_POSTHOG_HOST; the payload includes an anonymous ID and basic package and runtime details.
- The CLI asks for telemetry consent before emitting command telemetry.
- The updater checks the npm registry for this package's latest version.
Evidence against
- No evidence inspected shows credential collection, broad project mutation, or execution of a remote payload. The postinstall telemetry is consent-gated and fail-soft.
