AI Security Review
scanned 7d ago · by lpm-firewall-aiSource inspection found a postinstall telemetry hook, but it exits unless the shared config already records telemetry consent. Runtime credential transfers are associated with explicit CLI operations and Extenshi service endpoints; the flagged static indicators did not establish a separate attack.
Static reason
One or more suspicious static signals were detected.; previous stored version diff introduced dangerous source
Trigger
The postinstall hook runs during package installation; its event path requires a prior telemetry opt-in. API requests occur during CLI operations.
Impact
No unconsented collection, credential theft, or other concrete attack behavior was established.
Mechanism
The hook checks the saved telemetry setting before sending limited installation metadata to PostHog. Runtime API calls attach the configured key to Extenshi BFF requests for the selected operation.
AI rationale
Source inspection found a postinstall telemetry hook, but it exits unless the shared config already records telemetry consent. Runtime credential transfers are associated with explicit CLI operations and Extenshi service endpoints; the flagged static indicators did not establish a separate attack.

Decision evidence
public snapshotAI called this Clean at 91.0% confidence as Benign with low false-positive risk.
Evidence for AI clean decision
- The postinstall hook is declared in the manifest, but its telemetry send is gated on previously recorded telemetry consent; absent consent exits the hook.
- Runtime API keys are sent with explicit CLI operations to Extenshi BFF endpoints, and Pay sends use its configured BFF URL.
- The reviewed modules and prepared dependencies support extension scanning, publishing, reports, screenshots, and local asset work; no separate attack behavior was identified.
