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. The flagged phone file contains phone-number metadata, while the reachable network and upload behavior supports the calendar widget. The package documents visitor consent for third-party pixels and exposes tracking controls; I found no concrete attack behavior. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 89.0% - **Started:** 2026-10-30T21:06:58.201Z - **Finished:** 2026-10-30T21:08:41.908Z - **Download time:** 1523 ms - **Static scan time:** 6158 ms - **AI review time:** 96024 ms - **Total time:** 103707 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 attack identified; observed network, tracking, and upload behavior supports the calendar widget. - **Trigger:** Import exposes the widget API; configuration fetches and upload callbacks occur when the widget is used. - **Impact:** No harmful impact identified. - **Review source:** ai\_review - **Reviewed:** 2026-10-30T21:08:41.908Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The bundle loads calendar configuration from its API base, handles widget context, and delegates uploads to the host application's callback. - **Rationale:** The flagged phone file contains phone-number metadata, while the reachable network and upload behavior supports the calendar widget. The package documents visitor consent for third-party pixels and exposes tracking controls; I found no concrete attack behavior. ### Review decision - **Verdict:** Clean - **Confidence:** 89.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** The manifest describes a Svelte calendar component and routes imports to its calendar bundles., The declared lifecycle scripts are prepare and prepublishOnly; no preinstall, install, or postinstall hook is declared., The flagged phone.js file begins with country calling code data., Runtime tracking uses widget and venue IDs; host page context is accepted only when the tracking predicate is true, and the README documents visitor consent for third-party pixels., The calendar fetches widget configuration through its API base, consistent with its purpose., The image uploader invokes an application-provided upload callback. ## Affected versions and remediation This report applies to @getmicdrop/venue-calendar@4.3.139. - Review the evidence and your use of @getmicdrop/venue-calendar@4.3.139 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.
