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. Scanner claims of credential exfiltration conflate deliberate, user-invoked authenticated webhook and reporting API requests with theft. Source inspection found no lifecycle execution, hidden payload, dynamic execution, or unconsented data transfer. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 96.0% - **Started:** 2026-08-06T14:59:30.702Z - **Finished:** 2026-08-06T15:00:09.404Z - **Download time:** 503 ms - **Static scan time:** 275 ms - **AI review time:** 37924 ms - **Total time:** 38702 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 confirmed malicious attack surface. Network, upload, and subprocess behavior belongs to explicitly invoked Playwright testing/reporting utilities and is gated by caller configuration. - **Trigger:** Explicit use of webhook, reporter, visual-test, or report-upload utilities - **Impact:** No unconsented installation-time execution, credential harvesting, or persistence found. - **Evidence paths:** package.json, dist/index.js, dist/webhook.js, dist/api-worker-client.js, dist/reporter/local-test.js, dist/reporter/uploader.js - **Review source:** ai\_review - **Reviewed:** 2026-08-06T15:00:09.404Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** configured test-service API calls and Playwright report generation - **Rationale:** Scanner claims of credential exfiltration conflate deliberate, user-invoked authenticated webhook and reporting API requests with theft. Source inspection found no lifecycle execution, hidden payload, dynamic execution, or unconsented data transfer. - **Network endpoints:** https://webhook.site, https://inbox.empirical.run, https://api.empirical.run, https://telemetry-worker.empirical-run.workers.dev ### Review decision - **Verdict:** Clean - **Confidence:** 96.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence against:** package.json has no preinstall/install/postinstall hooks., dist/webhook.js only contacts webhook providers when exported functions are called., API keys are used as Authorization/API-Key headers to configured provider endpoints, not harvested or forwarded., dist/reporter/local-test.js runs a fixed Playwright report command only when explicitly invoked., Root dist/index.js only exports utilities; it performs no network or child-process action on import., Report uploads require explicit test-run/storage environment configuration. ## Affected versions and remediation This report applies to @empiricalrun/playwright-utils@0.57.0. - Review the evidence and your use of @empiricalrun/playwright-utils@0.57.0 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.
