Lints UBL and CII invoice XML against EN 16931 and the national e-invoicing mandates that are live in 2026
AI Security Review
scanned 11d ago · by lpm-firewall-aiSource inspection found a local invoice checker, product license validation, and limited package-aligned usage events gated for interactive use. The inspected network behavior does not establish credential theft or another concrete attack.
Static reason
High-risk behavior combination matched malicious policy.; previous stored version diff introduced dangerous source
Trigger
Invoking the CLI runs checks; paid operations validate a license, and interactive free or failed-license flows may send a usage event.
Impact
The inspected behavior supports ordinary linting, licensing and limited usage measurement; no concrete attack effect was established.
Mechanism
The checker evaluates invoice text locally. License keys go to Polar's validation endpoint, while usage events contain product and event labels.
AI rationale
Source inspection found a local invoice checker, product license validation, and limited package-aligned usage events gated for interactive use. The inspected network behavior does not establish credential theft or another concrete 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 manifest declares cli.js as the package command entry point.
- The engine exports an invoice check function and rule data.
- License validation sends the supplied or saved key with organization and benefit identifiers to Polar's license validation endpoint.
- Paid CLI operations invoke the license check.
- Usage events contain the product slug, source and reason, and the CLI sends them to the package service only when telemetry opt-outs and non-interactive conditions do not apply.
- The license event path also checks telemetry opt-outs and requires a terminal or MCP session.
