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 clear-canvas command deletes all localStorage for the origin, a broader destructive effect than clearing the editor canvas implies. The action requires the user to invoke it and confirm, so this is suspicious rather than malicious. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 94.0% - **Started:** 2026-10-31T04:24:36.160Z - **Finished:** 2026-10-31T04:25:23.132Z - **Download time:** 1521 ms - **Static scan time:** 3538 ms - **AI review time:** 41911 ms - **Total time:** 46972 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 page builder’s clear-canvas action can erase all browser local storage for the site, beyond the editor canvas. - **Trigger:** A user invokes the page builder’s canvas-clear command and confirms the prompt. - **Impact:** Other application data stored in localStorage for the same origin may be lost. - **Evidence paths:** fesm2022/inchurch-matcha-components.mjs - **Review source:** ai\_review - **Reviewed:** 2026-10-31T04:25:23.132Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** After clearing the editor canvas, the command calls localStorage.clear() without limiting deletion to editor-owned keys. - **Rationale:** The clear-canvas command deletes all localStorage for the origin, a broader destructive effect than clearing the editor canvas implies. The action requires the user to invoke it and confirm, so this is suspicious rather than malicious. - **Files touched:** fesm2022/inchurch-matcha-components.mjs - **Network endpoints:** unpkg.com, uicdn.toast.com ### Review decision - **Verdict:** Suspicious - **Confidence:** 94.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Unknown - **False-positive risk:** Medium - **Evidence for warning:** The page builder’s “canvas-clear” command asks for confirmation, clears the canvas, then calls localStorage.clear(), which removes all local storage for the site’s origin., The page builder loads its editor assets in ngAfterViewInit and uses an unversioned unpkg.com URL; this path is tied to using the editor component., The package manifest declares no lifecycle scripts. - **Evidence against:** The storage-clearing code is attached to an explicit canvas-clear action and runs only after a confirmation prompt., The manifest exposes an Angular component bundle and declares only tslib as a dependency, consistent with a UI component library., Bidi controls flagged by the scanner occur in country-name strings containing Arabic text. ## Affected versions and remediation This report applies to @inchurch/matcha-components@22.36.0. - Review the evidence and your use of @inchurch/matcha-components@22.36.0 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.
