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 confirmed canvas-clear action also wipes the embedding site's entire localStorage, creating a destructive side effect beyond the user's stated action. This is a warning-level concern because the wipe requires an explicit confirmation and no malicious collection or transmission was identified. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 96.0% - **Started:** 2026-10-31T04:26:39.106Z - **Finished:** 2026-10-31T04:27:32.143Z - **Download time:** 1019 ms - **Static scan time:** 3555 ms - **AI review time:** 48462 ms - **Total time:** 53037 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-canvas action also wipes all local storage for the embedding site. - **Trigger:** A user selects clear canvas and accepts the confirmation prompt in MatchaPageBuilder. - **Impact:** Other application state stored for the same site, potentially including session or preference data, is also deleted. - **Evidence paths:** fesm2022/inchurch-matcha-components.mjs - **Review source:** ai\_review - **Reviewed:** 2026-10-31T04:27:32.143Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** After clearing the GrapesJS canvas, the code calls localStorage.clear(). - **Rationale:** The confirmed canvas-clear action also wipes the embedding site's entire localStorage, creating a destructive side effect beyond the user's stated action. This is a warning-level concern because the wipe requires an explicit confirmation and no malicious collection or transmission was identified. - **Files touched:** fesm2022/inchurch-matcha-components.mjs ### Review decision - **Verdict:** Suspicious - **Confidence:** 96.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Unknown - **False-positive risk:** Medium - **Evidence for warning:** The page builder asks for confirmation before clearing its canvas, then calls localStorage.clear(), which removes every local storage key for the embedding site., The clear behavior is part of the browser-based page-builder component, whose initialization runs in ngAfterViewInit. - **Evidence against:** The manifest declares no lifecycle scripts., The storage wipe requires a user to confirm the canvas-clear action; no credential collection or external data transfer was identified. ## Affected versions and remediation This report applies to @inchurch/matcha-components@22.33.0. - Review the evidence and your use of @inchurch/matcha-components@22.33.0 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.
