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 concrete attack behavior. The flagged webhook and subprocess code has explicit test utility behavior and no confirmed unrelated credential destination. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 95.0% - **Started:** 2026-10-09T08:41:00.544Z - **Finished:** 2026-10-09T08:41:51.252Z - **Download time:** 778 ms - **Static scan time:** 438 ms - **AI review time:** 49492 ms - **Total time:** 50708 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 inspected network and process activity is tied to explicit webhook utilities, local report generation, or an upstream test harness. - **Trigger:** A caller invokes the webhook API or the reporter finalizes a local test run; the oracle runs separately against a supplied Playwright clone. - **Impact:** No confirmed secret harvesting, unrelated credential forwarding, or malicious install-time behavior was found. - **Review source:** ai\_review - **Reviewed:** 2026-10-09T08:41:51.252Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Webhook credentials are sent to webhook.site for its token API, while reporter subprocess execution invokes Playwright's merge-reports command in the caller's working directory. - **Rationale:** Source inspection found no install lifecycle hook or concrete attack behavior. The flagged webhook and subprocess code has explicit test utility behavior and no confirmed unrelated credential destination. - **Files touched:** package.json, dist/webhook.js, dist/reporter/local-test.js, upstream-oracle/run.mjs, dist/api-worker-client.js - **Network endpoints:** https://webhook.site, https://api.empirical.run ### Review decision - **Verdict:** Clean - **Confidence:** 95.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** package.json exposes the library through dist/index.js and lists development and test scripts, with no install lifecycle hook., The webhook API creates and queries webhook.site resources when its exported functions are called; it uses a caller-provided webhook.site key for that service., The API client defaults to api.empirical.run and allows the caller to configure its base URL., The local reporter runs Playwright's merge-reports command to produce local HTML and JSON reports., The upstream oracle runs npm tests against a supplied Playwright clone. ## Affected versions and remediation This report applies to @empiricalrun/playwright-utils@0.62.0. - Review the evidence and your use of @empiricalrun/playwright-utils@0.62.0 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.
