This report does not record a matching static-policy override reason. 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.

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 makes authenticated requests only to its fixed MockForMe service when its features are used. - **Trigger:** A caller mounts the widget and supplies or submits a MockForMe token. - **Impact:** User-supplied MockForMe credentials and feature data are sent to the corresponding MockForMe service. - **Review source:** ai\_review - **Reviewed:** 2026-09-19T18:53:42.682Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Browser widget requests to a fixed service endpoint. - **Rationale:** The scanner's exfiltration label matches ordinary authenticated service requests to a fixed package-aligned endpoint, not a hidden or unrestricted recipient. No install hook, import-time execution, credential harvesting, external payload loading, or destructive behavior was found. - **Network endpoints:** https://api.mockforme.com ### Review decision - **Verdict:** Clean - **Confidence:** 88.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Final policy explanation:** The AI recommended clean, but the final policy action is warn. This report does not record a matching static-policy override reason. - **Evidence for AI clean decision:** The manifest contains only browser import entrypoints and no lifecycle scripts., The widget uses a fixed MockForMe API host; its authenticated proxy requests send the token provided to the widget to that same service., The flagged lazy bundle is an identifiable JSON editor dependency, not an opaque payload., The public entrypoint only re-exports widget APIs and does not invoke the widget on import. - **Evidence against:** Analytics is enabled by default and includes the supplied MockForMe token in requests to the MockForMe API. ## Affected versions and remediation This report applies to mfm-widget-newer@15.7.0. - Review the evidence and your use of mfm-widget-newer@15.7.0 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.
