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 hook or concrete attack behavior. The scanner's webhook finding maps to explicit test helpers, while the dynamic overlay cache and telemetry are tied to Playwright testing and the package's API service. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 93.0% - **Started:** 2026-10-16T02:09:07.562Z - **Finished:** 2026-10-16T02:10:28.989Z - **Download time:** 1276 ms - **Static scan time:** 438 ms - **AI review time:** 79712 ms - **Total time:** 81427 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. The flagged network calls, telemetry, and cached overlay code support the package's Playwright testing features. - **Trigger:** Consumers invoke the exported helpers or use the Playwright test fixture; overlay assistance runs when a click or hover is blocked by an intercepting element. - **Impact:** These operations support testing and reporting; the inspected source does not establish credential theft or another concrete attack. - **Review source:** ai\_review - **Reviewed:** 2026-10-16T02:10:28.989Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The helpers contact the selected webhook provider, telemetry uses the Empirical API when a project key is present, and overlay code is generated for and matched to a page element. - **Rationale:** Source inspection found no install hook or concrete attack behavior. The scanner's webhook finding maps to explicit test helpers, while the dynamic overlay cache and telemetry are tied to Playwright testing and the package's API service. - **Files touched:** package.json, dist/webhook.js, dist/api-worker-client.js, dist/telemetry.js, dist/test/scripts/pw-locator-patch/dismiss-overlays/cache.js, dist/test/scripts/pw-locator-patch/highlight/click.js, dist/reporter/local-test.js, dist/reporter/incremental-blob-reporter.js, upstream-oracle/run.mjs - **Network endpoints:** https://api.empirical.run, https://webhook.site, https://inbox.empirical.run ### Review decision - **Verdict:** Clean - **Confidence:** 93.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** package.json exposes the library and test helpers, and lists no install lifecycle hook; upstream-oracle/run.mjs is a separate test harness., The webhook helpers create and query webhook.site or Empirical inbox tokens through exported calls, using API keys for those services., ApiWorkerClient sends its Empirical project key to the Empirical API by default; DASHBOARD\_DOMAIN can select another API host., Overlay code is generated by the overlay agent, cached against an element description, and run only for a matching overlay during a Playwright interaction., The local report helper runs only Playwright's merge-reports command, and its caller gates it on local testing., Telemetry requires EMPIRICALRUN\_API\_KEY and sends test-run event properties to the API worker. - **Evidence against:** The overlay cache compiles a matching stored code string with AsyncFunction and executes it with the Playwright page., Overlay telemetry includes page text and test identifiers, sent to the package's API worker when the project key is present. ## Affected versions and remediation This report applies to @empiricalrun/playwright-utils@0.61.2. - Review the evidence and your use of @empiricalrun/playwright-utils@0.61.2 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.
