Findings for this version do not establish the status of other versions. AI assessment: suspicious; recommendation: downgrade to warn. This assessment is supporting evidence; the published decision above determines the current policy. The bidi characters are part of Arabic country labels, but the page-builder clear action has an overbroad destructive side effect: confirming a canvas clear also erases all origin localStorage. This is a user-triggered data-loss risk, so it warrants a warning rather than a malicious-package block. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 90.0% - **Started:** 2026-10-31T04:23:56.116Z - **Finished:** 2026-10-31T04:24:36.073Z - **Download time:** 509 ms - **Static scan time:** 7082 ms - **AI review time:** 32365 ms - **Total time:** 39957 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:** The confirmed canvas-clear action also clears all local storage for the current origin. - **Trigger:** A user clicks the page builder's canvas-clear command and confirms the prompt. - **Impact:** Other application state stored in localStorage on the same origin may be lost. - **Evidence paths:** fesm2022/inchurch-matcha-components.mjs - **Review source:** ai\_review - **Reviewed:** 2026-10-31T04:24:36.073Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** After clearing the editor canvas, a timer calls localStorage.clear() without limiting the deletion to page-builder data. - **Rationale:** The bidi characters are part of Arabic country labels, but the page-builder clear action has an overbroad destructive side effect: confirming a canvas clear also erases all origin localStorage. This is a user-triggered data-loss risk, so it warrants a warning rather than a malicious-package block. - **Files touched:** fesm2022/inchurch-matcha-components.mjs - **Network endpoints:** https://unpkg.com/matcha-components/assets/page-builder ### Review decision - **Verdict:** Suspicious - **Confidence:** 90.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Unknown - **False-positive risk:** Medium - **Evidence for warning:** The page builder asks the user to confirm clearing the canvas, then runs the canvas-clear command and calls localStorage.clear(), deleting all local storage for the origin., The page-builder component loads its editor assets from the matcha-components path on unpkg when its view initializes., The flagged bidi characters occur in Arabic country names in the phone-country list. - **Evidence against:** The manifest identifies this as an Angular component library with no lifecycle scripts., The broad storage deletion is behind an explicit canvas-clear action and confirmation. ## Affected versions and remediation This report applies to @inchurch/matcha-components@22.36.2. - Review the evidence and your use of @inchurch/matcha-components@22.36.2 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.
