Static policy retained a warning. The static scanner classified the package as malicious with confidence of at least 85%. A critical static finding has confidence of at least 90%. These conditions do not mean that the AI confirmed malicious behavior. AI assessment: clean; recommendation: mark clean. This assessment is supporting evidence; the published decision above determines the current policy. No install-time or hidden attack surface was identified. The package is a browser widget whose network calls target the MockForMe API and dashboard. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 84.0% - **Started:** 2026-09-26T12:52:56.612Z - **Finished:** 2026-09-26T12:53:48.138Z - **Download time:** 508 ms - **Static scan time:** 1428 ms - **AI review time:** 49590 ms - **Total time:** 51526 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 install-time or hidden attack surface was identified. The package is a browser widget whose network calls target the MockForMe API and dashboard. - **Trigger:** A consuming app imports the widget; nothing runs on npm install. - **Impact:** No credential theft, remote payload execution, persistence, or agent-control mutation was established. - **Review source:** ai\_review - **Reviewed:** 2026-09-26T12:53:48.138Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The entry re-exports the widget chunk, which talks to api.mockforme.com and stores widget settings in browser storage. - **Rationale:** Inspection found no lifecycle hooks, secret harvesting, or unrelated exfiltration. Storage and new Function use sit inside the imported MockForMe widget and do not form a concrete attack. - **Network endpoints:** https://api.mockforme.com, https://dashboard.mockforme.com ### Review decision - **Verdict:** Clean - **Confidence:** 84.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Final policy explanation:** The AI recommended clean. Static policy retained a warning. The static scanner classified the package as malicious with confidence of at least 85%. A critical static finding has confidence of at least 90%. These conditions do not mean that the AI confirmed malicious behavior. - **Evidence for AI clean decision:** package.json is an ESM widget with main and module pointing at dist/mfm-widget-new.es.js and has no install lifecycle scripts., The widget chunk sets its API base to https://api.mockforme.com and dashboard to https://dashboard.mockforme.com, matching a MockForMe client., dist/chunks/JsonEditorLazyBundle-CO\_RjMpQ.js is a jsoneditor bundle imported from the widget chunk, not an install-time payload. - **Evidence against:** A new Function call parses caller-supplied selector text inside the widget UI., Storage helpers read and write named localStorage, sessionStorage, and cookie keys for widget state. ## Affected versions and remediation This report applies to mfm-widget-newer@17.3.0. - Review the evidence and your use of mfm-widget-newer@17.3.0 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.
