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 bundle contains an overbroad destructive side effect: confirming a canvas clear also wipes the host application's entire local storage. This is user-triggered and not an install-time or import-time attack, so it warrants a warning rather than a publish block. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 90.0% - **Started:** 2026-10-31T04:28:45.561Z - **Finished:** 2026-10-31T04:29:38.862Z - **Download time:** 1513 ms - **Static scan time:** 3568 ms - **AI review time:** 48220 ms - **Total time:** 53301 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 hosting origin. - **Trigger:** A user invokes the editor's canvas-clear command and confirms the prompt. - **Impact:** Unrelated application state stored under the same origin may be lost. - **Evidence paths:** fesm2022/inchurch-matcha-components.mjs - **Review source:** ai\_review - **Reviewed:** 2026-10-31T04:29:38.862Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** After clearing the GrapesJS canvas, the command schedules localStorage.clear(). - **Rationale:** The bundle contains an overbroad destructive side effect: confirming a canvas clear also wipes the host application's entire local storage. This is user-triggered and not an install-time or import-time attack, so it warrants a warning rather than a publish block. - **Network endpoints:** unpkg.com, uicdn.toast.com ### Review decision - **Verdict:** Suspicious - **Confidence:** 90.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Unknown - **False-positive risk:** Medium - **Evidence for warning:** The page builder's canvas-clear command calls localStorage.clear(), removing every local storage key for the current origin., The clearing runs only after the user invokes canvas-clear and confirms a prompt., The manifest has no lifecycle scripts; its package entry is the Angular component bundle. - **Evidence against:** The bidi controls found in the bundle appear in Arabic country-name strings, consistent with right-to-left text display., The package is a UI component library, and the storage-clearing code is part of its page-builder editor. ## Affected versions and remediation This report applies to @inchurch/matcha-components@22.40.1. - Review the evidence and your use of @inchurch/matcha-components@22.40.1 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.
