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 package is not malicious, but its confirmed canvas-clear action wipes all same-origin local storage. Because this can delete unrelated application data and the editor disables its own storage manager, classify it as a destructive-action risk. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 89.0% - **Started:** 2026-10-31T04:25:34.574Z - **Finished:** 2026-10-31T04:26:18.712Z - **Download time:** 1016 ms - **Static scan time:** 3965 ms - **AI review time:** 39156 ms - **Total time:** 44138 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:** Canvas clearing can erase all local storage for the current origin, including unrelated application data. - **Trigger:** A user selects Clear canvas and confirms the prompt. - **Impact:** Unrelated same-origin app state, including stored settings or credentials, may be lost. - **Evidence paths:** fesm2022/inchurch-matcha-components.mjs - **Review source:** ai\_review - **Reviewed:** 2026-10-31T04:26:18.712Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The handler clears the editor canvas and then calls localStorage.clear() without limiting the deletion to editor data. - **Rationale:** The package is not malicious, but its confirmed canvas-clear action wipes all same-origin local storage. Because this can delete unrelated application data and the editor disables its own storage manager, classify it as a destructive-action risk. - **Files touched:** localStorage ### Review decision - **Verdict:** Suspicious - **Confidence:** 89.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Unknown - **False-positive risk:** Medium - **Evidence for warning:** The page builder's canvas-clear handler calls localStorage.clear(), removing all local storage for the current origin., That broad deletion runs after a confirmation to clear the canvas, so it can remove unrelated app data without happening automatically., The editor config sets storageManager: false, so clearing all origin storage is not needed for GrapesJS-managed persistence. - **Evidence against:** The package manifest has no install or lifecycle scripts and exposes an Angular component bundle., The destructive call is behind an explicit confirmation in the canvas-clear action., The bidi controls appear in localized Arabic country names, consistent with right-to-left display rather than concealed code. ## Affected versions and remediation This report applies to @inchurch/matcha-components@22.38.2. - Review the evidence and your use of @inchurch/matcha-components@22.38.2 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.
