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 canvas-clear command calls global localStorage.clear() after a prompt that only describes clearing the canvas, so unrelated host-application data may be deleted. This is a destructive side effect in an otherwise ordinary UI component library, so I classify it as suspicious rather than malicious. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 92.0% - **Started:** 2026-10-31T04:30:08.928Z - **Finished:** 2026-10-31T04:30:53.730Z - **Download time:** 1291 ms - **Static scan time:** 3696 ms - **AI review time:** 39814 ms - **Total time:** 44802 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:** A confirmed canvas-clear action can erase the host application’s entire origin-local storage. - **Trigger:** A user runs the page builder’s canvas-clear command and accepts its confirmation prompt. - **Impact:** Unrelated application state stored in localStorage may be lost. - **Evidence paths:** fesm2022/inchurch-matcha-components.mjs - **Review source:** ai\_review - **Reviewed:** 2026-10-31T04:30:53.730Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The command clears the editor canvas, then calls localStorage.clear() without limiting deletion to editor-owned keys. - **Rationale:** The canvas-clear command calls global localStorage.clear() after a prompt that only describes clearing the canvas, so unrelated host-application data may be deleted. This is a destructive side effect in an otherwise ordinary UI component library, so I classify it as suspicious rather than malicious. - **Files touched:** fesm2022/inchurch-matcha-components.mjs - **Network endpoints:** unpkg.com, viacep.com.br ### Review decision - **Verdict:** Suspicious - **Confidence:** 92.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The page builder’s confirmed “clean the canvas” action calls global localStorage.clear(), which can erase unrelated data saved by the host application on the same origin. - **Evidence against:** The clear operation is behind an explicit confirmation prompt and is part of the page builder’s canvas-clear command., The manifest exports an Angular component bundle and declares only tslib as a dependency; the inspected HTTP lookups serve component features such as CEP address lookup. ## Affected versions and remediation This report applies to @inchurch/matcha-components@22.40.7. - Review the evidence and your use of @inchurch/matcha-components@22.40.7 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.
