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. No confirmed malicious attack surface was established. The browser widget contains opt-in DOM-selection and MockForMe service features, but no install-time execution or unconsented credential harvesting was found. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 90.0% - **Started:** 2026-08-27T06:36:48.603Z - **Finished:** 2026-08-27T06:38:36.775Z - **Download time:** 251 ms - **Static scan time:** 1664 ms - **AI review time:** 106257 ms - **Total time:** 108172 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 was established. The browser widget contains opt-in DOM-selection and MockForMe service features, but no install-time execution or unconsented credential harvesting was found. - **Trigger:** A host application imports and uses the widget; relevant service requests require widget flows and a supplied token. - **Impact:** The feature can act on the host page when deliberately used, but the inspected source does not establish an unconsented attack chain. - **Evidence paths:** package.json, dist/mfm-widget-new.es.js, dist/chunks/widget-CmOpFdEx.js, dist/chunks/JsonEditorLazyBundle-C7-YQLdT.js, dist/chunks/html2canvas.esm-Dmi1NfiH.js - **Review source:** ai\_review - **Reviewed:** 2026-08-27T06:38:36.775Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Browser widget API calls and an explicit JavaScript-expression DOM selector. - **Rationale:** Source inspection found a browser-side MockForMe widget with package-aligned API calls and an explicit dynamic DOM-selector feature. It has no lifecycle hook or concrete malicious execution, persistence, theft, or exfiltration chain. - **Network endpoints:** https://api.mockforme.com ### Review decision - **Verdict:** Clean - **Confidence:** 90.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** The browser bundle contains a JavaScript-expression selector implemented with dynamic code generation., The widget sends token-authenticated requests to its declared MockForMe API, including AI and upload-related routes. - **Evidence against:** package.json has no lifecycle scripts or executable install hook., The only package entrypoint exports browser-widget APIs; no Node process, shell, filesystem, or child-process behavior was found., The dynamic-code path is explicitly named jsExpression and returns selected DOM elements, consistent with an opt-in widget feature., The API host is declared as MockForMe service configuration, not a concealed receiver. ## Affected versions and remediation This report applies to mfm-widget-newer@15.1.0. - Review the evidence and your use of mfm-widget-newer@15.1.0 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.
