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 page builder’s confirmed clear action calls localStorage.clear(), which can erase unrelated data stored by the embedding application. User confirmation limits the risk, but the deletion scope exceeds the stated canvas-clearing action. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 87.0% - **Started:** 2026-10-31T04:25:35.405Z - **Finished:** 2026-10-31T04:26:11.436Z - **Download time:** 761 ms - **Static scan time:** 3401 ms - **AI review time:** 31868 ms - **Total time:** 36031 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 clear command can erase all local storage for the embedding site’s origin. - **Trigger:** A user invokes “Clear canvas” and confirms the prompt. - **Impact:** Other application data stored in localStorage for that origin may also be deleted. - **Evidence paths:** fesm2022/inchurch-matcha-components.mjs - **Review source:** ai\_review - **Reviewed:** 2026-10-31T04:26:11.436Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** After clearing the canvas, the callback calls localStorage.clear(). - **Rationale:** The page builder’s confirmed clear action calls localStorage.clear(), which can erase unrelated data stored by the embedding application. User confirmation limits the risk, but the deletion scope exceeds the stated canvas-clearing action. - **Files touched:** fesm2022/inchurch-matcha-components.mjs ### Review decision - **Verdict:** Suspicious - **Confidence:** 87.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Unknown - **False-positive risk:** Medium - **Evidence for warning:** The page builder’s confirmed “Clear canvas” action runs localStorage.clear(), which removes all local storage for the browser origin, not only editor data., The package exports the Angular bundle as its default entry point. - **Evidence against:** The storage-clearing callback runs only after the user confirms the “Clear canvas” action., The bundle’s external requests are used for page-builder assets and a postal-code lookup feature; no credential collection or unrelated data transmission was identified. ## Affected versions and remediation This report applies to @inchurch/matcha-components@22.38.3. - Review the evidence and your use of @inchurch/matcha-components@22.38.3 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.
