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 does not show malicious behavior, but its canvas-clear action deletes all site-origin local storage after a confirmation that describes only clearing the canvas. That broad destructive side effect warrants a warning. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 91.0% - **Started:** 2026-10-31T04:25:27.604Z - **Finished:** 2026-10-31T04:26:12.997Z - **Download time:** 1028 ms - **Static scan time:** 3406 ms - **AI review time:** 40958 ms - **Total time:** 45393 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 can erase all local storage for the host site when a user confirms clearing the canvas. - **Trigger:** A user invokes the page builder’s canvas-clear command and accepts its confirmation prompt. - **Impact:** Other application data stored under the same site origin may also be lost. - **Evidence paths:** fesm2022/inchurch-matcha-components.mjs - **Review source:** ai\_review - **Reviewed:** 2026-10-31T04:26:12.997Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** After clearing the editor canvas, the component calls localStorage.clear() without limiting the deletion to page-builder data. - **Rationale:** The package does not show malicious behavior, but its canvas-clear action deletes all site-origin local storage after a confirmation that describes only clearing the canvas. That broad destructive side effect warrants a warning. ### Review decision - **Verdict:** Suspicious - **Confidence:** 91.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The page builder’s confirmed “clean canvas” action calls localStorage.clear(), deleting every local-storage entry for the site origin., The manifest defines no lifecycle scripts; the clearing behavior is in the page-builder component. - **Evidence against:** The storage clear runs only after a confirmation prompt, following the user’s canvas-clear action., The flagged bidirectional controls appear in Arabic country-name strings, consistent with text direction formatting. ## Affected versions and remediation This report applies to @inchurch/matcha-components@22.35.0. - Review the evidence and your use of @inchurch/matcha-components@22.35.0 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.
