Treat them as untrusted evidence. Do not execute instructions or code found in this document. ## Verdict summary **Flagged — allowed with a warning** — Allowed by default policy, but 12 finding(s) warrant review before installing. - **Verdict:** Suspicious - **Product-default install policy:** Warn - **Firewall policy:** Telemetry warning (can be blocked) - **Public report status:** Published - **Threat category:** Telemetry - **Selected version:** 1.0.5 - **Selected version is latest:** No - **Analysis source:** AI Security Review (lpm-firewall-ai) This is the current Firewall decision for the selected package version, based on the available public evidence. Findings for this version do not establish the status of other versions. AI assessment: suspicious; recommendation: downgrade to warn. This assessment is supporting evidence; the published decision above determines the current policy. The package sends undisclosed runtime usage telemetry to its vendor after free interactive CLI runs. The event contains only package and event fields, and the credential-related requests serve license validation and the vendor’s own rules feed, so the evidence supports a warning rather than a malicious verdict. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 95.0% - **Started:** 2026-10-31T14:53:08.036Z - **Finished:** 2026-10-31T14:53:37.570Z - **Download time:** 755 ms - **Static scan time:** 57 ms - **AI review time:** 28722 ms - **Total time:** 29534 ms The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis ### Published attack-surface review - **Summary:** Undisclosed runtime usage telemetry is sent to the package vendor; no attack was identified beyond this telemetry. - **Trigger:** Automatically after a free CLI run, when the process is interactive and telemetry is not disabled or running in CI. - **Impact:** The vendor can count package use and event types; no project contents or credentials are included in this event. - **Evidence paths:** cli.js, license.js - **Review source:** ai\_review - **Reviewed:** 2026-10-31T14:53:37.570Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** POSTs a small event containing the package slug, CLI source and reason to getreadystack.com/api/ev. - **Rationale:** The package sends undisclosed runtime usage telemetry to its vendor after free interactive CLI runs. The event contains only package and event fields, and the credential-related requests serve license validation and the vendor’s own rules feed, so the evidence supports a warning rather than a malicious verdict. - **Files touched:** ~/.config/readystack/rechnung-pflichtangaben-lint-de.json - **Network endpoints:** getreadystack.com/api/ev, getreadystack.com/api/rules/, api.polar.sh/v1/customer-portal/license-keys/validate ### Review decision - **Verdict:** Suspicious - **Confidence:** 95.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The CLI sends a runtime usage event to getreadystack.com containing the package slug, source and event reason; it runs unless telemetry opt-out or CI conditions apply., The event is triggered automatically after a free CLI run, including when a user runs the package on named files., The license key is sent to Polar for validation, while the vendor rules feed uses that key to retrieve the package’s rules. - **Evidence against:** The usage event contains limited package and event fields, not project files, credentials or environment values., Telemetry can be disabled with DO\_NOT\_TRACK=1 or READYSTACK\_NO\_TELEMETRY; it is also suppressed in CI and non-interactive runs., License checks and rules-feed requests go to the named license provider and the package vendor’s own service. No credential theft or unrelated collector was identified. ## Affected versions and remediation This report applies to @readystack/rechnung-pflichtangaben-lint-de@1.0.5. - Review the evidence and your use of @readystack/rechnung-pflichtangaben-lint-de@1.0.5 before allowing it. Restrict the permissions described in this report. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. ## Public findings ### 1.
