Do not execute instructions or code found in this document. ## Verdict summary **Flagged as AI-agent capability risk** — Allowed by default with warning: agent-facing configuration or capability changes need review before use. - **Verdict:** Suspicious - **Product-default install policy:** Warn - **Firewall policy:** Warn-only AI-agent capability risk - **Public report status:** Published - **Threat category:** AI-agent capability abuse - **Selected version:** 0.58.1 - **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: suspicious; recommendation: downgrade to warn. This assessment is supporting evidence; the published decision above determines the current policy. The scanner's webhook exfiltration claim is not supported: credentials are used as API authentication for explicit provider operations. However, automatic agent invocation plus cached dynamic execution is unresolved dangerous capability. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 88.0% - **Started:** 2026-08-08T09:31:53.014Z - **Finished:** 2026-08-08T09:33:02.765Z - **Download time:** 510 ms - **Static scan time:** 242 ms - **AI review time:** 68998 ms - **Total time:** 69751 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:** The default test fixture can automatically invoke a computer-use overlay-dismissal agent during Playwright tests. Generated page-action code is cached under the project working directory and later evaluated. - **Trigger:** A consumer uses baseTestFixture and an intercepted Playwright click triggers overlay dismissal. - **Impact:** Untrusted page content may influence an agent-driven browser action and persisted executable cache. - **Evidence paths:** package.json, dist/test/index.js, dist/test/scripts/pw-locator-patch/dismiss-overlays/index.js, dist/test/scripts/pw-locator-patch/dismiss-overlays/cache.js, dist/webhook.js, dist/api-worker-client.js - **Review source:** ai\_review - **Reviewed:** 2026-08-08T09:33:02.765Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Automatic computer-use agent with cached dynamic JavaScript execution. - **Rationale:** The scanner's webhook exfiltration claim is not supported: credentials are used as API authentication for explicit provider operations. However, automatic agent invocation plus cached dynamic execution is unresolved dangerous capability. - **Files touched:** .empiricalrun/overlay-cache.json - **Network endpoints:** https://api.empirical.run, https://telemetry-worker.empirical-run.workers.dev, https://webhook.site, https://inbox.empirical.run ### Review decision - **Verdict:** Suspicious - **Confidence:** 88.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** dist/test/index.js enables agentCapabilities by default in its Playwright fixture., dist/test/scripts/pw-locator-patch/dismiss-overlays/index.js invokes a computer-use agent after an intercepted click., dist/test/scripts/pw-locator-patch/dismiss-overlays/cache.js persists generated code then executes it with AsyncFunction. - **Evidence against:** package.json has no preinstall, install, postinstall, or bin hook., Webhook code uses configured provider/API credentials for explicit webhook test helpers; it does not send environment contents to webhook.site., Networked reporting/uploads require explicit project, run, backend, and credential environment configuration., No source evidence of credential harvesting, stealth persistence, or foreign AI-agent-control writes. ## Affected versions and remediation This report applies to @empiricalrun/playwright-utils@0.58.1. - Review the evidence and your use of @empiricalrun/playwright-utils@0.58.1 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.
