Do not execute instructions or code found in this document. ## Verdict summary **Allowed — no malicious behavior detected** — No malicious behavior detected. 16 low-signal pattern(s) reviewed. - **Verdict:** Clean - **Product-default install policy:** Allow - **Firewall policy:** No policy match - **Public report status:** Published - **Threat category:** None published - **Selected version:** 0.64.0 - **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: clean; recommendation: mark clean. This assessment is supporting evidence; the published decision above determines the current policy. Source inspection found no install lifecycle hook or confirmed attack behavior. The flagged network and subprocess operations are consistent with caller-invoked webhook and reporting features, and their credentials are sent to the corresponding service or Empirical API proxy. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 91.0% - **Started:** 2026-10-28T04:03:09.254Z - **Finished:** 2026-10-28T04:03:46.584Z - **Download time:** 769 ms - **Static scan time:** 427 ms - **AI review time:** 36133 ms - **Total time:** 37330 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:** No attack was identified in the inspected package source. Network access and subprocess execution support the library’s webhook and Playwright reporting functions. - **Trigger:** A caller invokes the exported webhook helpers or the local report merge helper. - **Impact:** The inspected behavior creates and queries webhook endpoints or generates local reports; it does not establish credential theft or another attack. - **Review source:** ai\_review - **Reviewed:** 2026-10-28T04:03:46.584Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Webhook requests use configured API credentials for the named service or Empirical proxy; report merging runs Playwright’s merge-reports command in the supplied working directory. - **Rationale:** Source inspection found no install lifecycle hook or confirmed attack behavior. The flagged network and subprocess operations are consistent with caller-invoked webhook and reporting features, and their credentials are sent to the corresponding service or Empirical API proxy. - **Files touched:** package.json, dist/index.js, dist/webhook.js, dist/reporter/local-test.js, dist/api-worker-client.js - **Network endpoints:** https://webhook.site, https://api.empirical.run, https://inbox.empirical.run ### Review decision - **Verdict:** Clean - **Confidence:** 91.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** package.json exposes the library entry point and contains development and build scripts, with no install lifecycle hook., The generated OpenAPI file contains TypeScript path declarations., The three inspected dependency manifests contain test scripts but no install lifecycle hooks; their cited source exports retry, authentication-token, and logging helpers., The webhook module creates or queries webhook services only through exported calls, using configured service credentials for the webhook.site API or the Empirical API proxy., The reporter’s local merge helper invokes Playwright’s merge-reports command in the caller-supplied working directory. ## Affected versions and remediation This report applies to @empiricalrun/playwright-utils@0.64.0. - Review the evidence and your use of @empiricalrun/playwright-utils@0.64.0 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.
