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 shows a Playwright utility package with user-invoked, credential-gated provider and reporting integrations. The static credential-exfiltration and runtime-install labels are not supported as malicious behavior. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 94.0% - **Started:** 2026-08-14T05:43:45.920Z - **Finished:** 2026-08-14T05:45:24.904Z - **Download time:** 513 ms - **Static scan time:** 383 ms - **AI review time:** 98088 ms - **Total time:** 98984 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, storage upload, and report-merging features are explicit library/reporter capabilities gated by user configuration or invocation. - **Trigger:** Consumer calls webhook/reporting helpers or configures the reporter. - **Impact:** No unconsented install-time execution or credential exfiltration established. - **Evidence paths:** package.json, dist/index.js, dist/webhook.js, dist/api-worker-client.js, dist/telemetry.js, dist/reporter/uploader.js, dist/reporter/local-test.js, dist/auth/index.js - **Review source:** ai\_review - **Reviewed:** 2026-08-14T05:45:24.904Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** configured webhook, API, telemetry, and test-report operations - **Rationale:** Source inspection shows a Playwright utility package with user-invoked, credential-gated provider and reporting integrations. The static credential-exfiltration and runtime-install labels are not supported as malicious behavior. - **Network endpoints:** https://webhook.site, https://api.empirical.run, https://reports-r2.empirical.run ### Review decision - **Verdict:** Clean - **Confidence:** 94.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** Manifest exposes library/reporting entrypoints and contains no lifecycle hook., Webhook calls occur only inside exported async helpers and require a configured provider key., API client sends its configured Empirical API key only as an Authorization header to its configured base URL., Report upload is disabled unless several explicit project, run, backend, and storage-credential environment variables are set., The child-process finding runs a fixed Playwright report-merge command in local-test flow. - **Evidence against:** No install-time execution, hidden downloader, dynamic code execution, or persistence mechanism found., No evidence that arbitrary environment variables, auth-state files, or credentials are harvested and sent to an attacker-controlled endpoint., Scanner's webhook credential-exfiltration label conflates explicit authenticated provider API use with credential theft. ## Affected versions and remediation This report applies to @empiricalrun/playwright-utils@0.58.3. - Review the evidence and your use of @empiricalrun/playwright-utils@0.58.3 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.
