Do not execute instructions or code found in this document. ## Verdict summary **Flagged — allowed with a warning** — Allowed by default policy, but 16 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:** 0.66.1 - **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 content-bearing overlay and test telemetry to its own service when the related feature runs, with no telemetry disclosure found in the README. The behavior is suspicious rather than malicious because it uses the package's service and does not exfiltrate credentials to a foreign host. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 87.0% - **Started:** 2026-11-03T11:38:49.006Z - **Finished:** 2026-11-03T11:40:01.455Z - **Download time:** 758 ms - **Static scan time:** 447 ms - **AI review time:** 71244 ms - **Total time:** 72449 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 telemetry sends overlay content and test context to the package's service. - **Trigger:** When the overlay-dismissal feature runs and EMPIRICALRUN\_API\_KEY is set. - **Impact:** Overlay text or test context containing sensitive information may be disclosed to Empirical without a telemetry disclosure found in the README. - **Evidence paths:** dist/telemetry.js, dist/test/scripts/pw-locator-patch/dismiss-overlays/index.js, dist/api-worker-client.js - **Review source:** ai\_review - **Reviewed:** 2026-11-03T11:40:01.455Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The feature sends an overlay.dismissed event, including page text and test details, to the telemetry endpoint using the Empirical API client. - **Rationale:** The package sends content-bearing overlay and test telemetry to its own service when the related feature runs, with no telemetry disclosure found in the README. The behavior is suspicious rather than malicious because it uses the package's service and does not exfiltrate credentials to a foreign host. - **Network endpoints:** https://api.empirical.run/api/v1/telemetry/track ### Review decision - **Verdict:** Suspicious - **Confidence:** 87.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Unknown - **False-positive risk:** Medium - **Evidence for warning:** Telemetry is sent to /api/v1/telemetry/track when EMPIRICALRUN\_API\_KEY is set., The overlay.dismissed event includes overlay text and description, the failing locator, project and repository names, and test context., The overlay-dismissal flow collects that text and calls the telemetry function during feature execution., The API client defaults to https://api.empirical.run and permits a user-configured DASHBOARD\_DOMAIN. - **Evidence against:** The telemetry requires the package's Empirical API key and goes to its own service by default., The inspected manifest scripts are build, test, lint and development tasks; no install lifecycle hook was found., The flagged npx command runs Playwright's merge-reports command only from the reporter's local-testing path. ## Affected versions and remediation This report applies to @empiricalrun/playwright-utils@0.66.1. - Review the evidence and your use of @empiricalrun/playwright-utils@0.66.1 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.
