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:** 2.9.0 - **Selected version is latest:** Yes - **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 automatically gathers browser and device traits, including a local IP address, and sends the fingerprint with form submissions without an evident disclosure or opt-in. This is suspicious telemetry; the ordinary form submission and selected-file upload flows otherwise fit the package's purpose. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 91.0% - **Started:** 2026-11-03T14:37:41.227Z - **Finished:** 2026-11-03T14:38:33.811Z - **Download time:** 520 ms - **Static scan time:** 149 ms - **AI review time:** 51915 ms - **Total time:** 52584 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 browser fingerprint collection is included with form submissions. - **Trigger:** The fingerprint collection starts when the package entry point is loaded; results are sent when a form is submitted. - **Impact:** The form service receives identifying browser data beyond the fields a user submits, which can enable tracking across submissions. - **Evidence paths:** index.js, src/fingerprint.js, src/Form.vue - **Review source:** ai\_review - **Reviewed:** 2026-11-03T14:38:33.811Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The module gathers browser and device traits, including a local IP address, and Form.vue adds the resulting fingerprint to the submission payload. - **Rationale:** The package automatically gathers browser and device traits, including a local IP address, and sends the fingerprint with form submissions without an evident disclosure or opt-in. This is suspicious telemetry; the ordinary form submission and selected-file upload flows otherwise fit the package's purpose. - **Network endpoints:** api.lucien.ai, \/api/v2/submissions/{form\_id} ### Review decision - **Verdict:** Suspicious - **Confidence:** 91.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The package entry point imports the fingerprint module when loaded., The fingerprint module collects browser and device traits, including a local IP address obtained through WebRTC., Fingerprint results are attached to form data sent automatically when a user submits a form., The manifest's prepare script is empty. - **Evidence against:** Form submissions are sent to the form's configured server as part of the package's core function., Private file uploads use the package API and a signed upload URL after a file is selected. ## Affected versions and remediation This report applies to lucien-form-builder@2.9.0. - Review the evidence and your use of lucien-form-builder@2.9.0 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.
