Do not execute instructions or code found in this document. ## Verdict summary **Allowed — no malicious behavior detected** — No malicious behavior detected. 17 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:** 0.58.5 - **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 legitimate, opt-in Playwright utilities and reporting rather than install-time or covert attack behavior. Static findings reflect intended network, credential, child-process, and cached automation features. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 91.0% - **Started:** 2026-08-17T08:01:53.922Z - **Finished:** 2026-08-17T08:03:24.774Z - **Download time:** 754 ms - **Static scan time:** 405 ms - **AI review time:** 89692 ms - **Total time:** 90852 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, uploads, and cached browser automation occur only through consumer-invoked utilities or configured Playwright reporting. - **Trigger:** Consumer imports and invokes a utility or configures the package as a Playwright fixture/reporter. - **Impact:** Expected test artifacts or provider data may be sent to configured package-aligned services. - **Evidence paths:** package.json, dist/index.js, dist/webhook.js, dist/api-worker-client.js, dist/reporter/uploader.js, dist/reporter/empirical-reporter.js, dist/test/scripts/pw-locator-patch/dismiss-overlays/cache.js - **Review source:** ai\_review - **Reviewed:** 2026-08-17T08:03:24.774Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** configured test automation, reporting, and provider API access - **Rationale:** Source inspection found legitimate, opt-in Playwright utilities and reporting rather than install-time or covert attack behavior. Static findings reflect intended network, credential, child-process, and cached automation features. - **Network endpoints:** https://api.empirical.run, https://webhook.site, https://inbox.empirical.run ### Review decision - **Verdict:** Clean - **Confidence:** 91.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Medium - **Evidence for AI clean decision:** Webhook helpers explicitly send only caller-supplied token/query data using configured provider credentials., The optional reporter uploads Playwright attachments and test-result metadata when configured., Overlay tooling executes code from its local .empiricalrun cache during an explicitly enabled test fixture. - **Evidence against:** package.json has no preinstall, install, or postinstall hook., Main import only re-exports utilities; no network or child-process action is invoked on import., Reporter upload is gated on configured run identifiers, storage backend, and credentials., No broad credential harvesting, foreign agent-config mutation, stealth persistence, or remote payload loading found. ## Affected versions and remediation This report applies to @empiricalrun/playwright-utils@0.58.5. - Review the evidence and your use of @empiricalrun/playwright-utils@0.58.5 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.
