Do not execute instructions or code found in this document. ## Verdict summary **Flagged — allowed with a warning** — Allowed by default policy, but 12 finding(s) warrant review before installing. - **Verdict:** Suspicious - **Product-default install policy:** Warn - **Firewall policy:** Matched warn-list - **Public report status:** Published - **Threat category:** Destructive Action - **Selected version:** 22.40.3 - **Selected version is latest:** No - **Analysis source:** AI Security Review (lpm-firewall-ai) This is the current Firewall decision for the selected package version, based on the available public evidence. 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 clear-canvas command performs an origin-wide local-storage wipe after a confirmation that describes only clearing the canvas. This is a potentially destructive, unexpectedly broad side effect, so I recommend a warning rather than treating the package as malicious. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 91.0% - **Started:** 2026-10-31T04:29:32.266Z - **Finished:** 2026-10-31T04:30:16.741Z - **Download time:** 764 ms - **Static scan time:** 3567 ms - **AI review time:** 40143 ms - **Total time:** 44475 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’s clear-canvas action also erases all local storage for the browser origin, creating a risk of unintended data loss. - **Trigger:** A user invokes the canvas-clear command and confirms the prompt. - **Impact:** Unrelated application data stored under the same origin may be lost. - **Evidence paths:** fesm2022/inchurch-matcha-components.mjs - **Review source:** ai\_review - **Reviewed:** 2026-10-31T04:30:16.741Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** After clearing the GrapesJS canvas, the component calls localStorage.clear() without limiting deletion to page-builder data. - **Rationale:** The clear-canvas command performs an origin-wide local-storage wipe after a confirmation that describes only clearing the canvas. This is a potentially destructive, unexpectedly broad side effect, so I recommend a warning rather than treating the package as malicious. - **Files touched:** Browser origin localStorage (all keys) ### Review decision - **Verdict:** Suspicious - **Confidence:** 91.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Unknown - **False-positive risk:** Medium - **Evidence for warning:** After a generic “clean the canvas” confirmation, the page builder clears the canvas and calls localStorage.clear(), which removes every local-storage key for the current origin., The manifest identifies an Angular ESM component library and declares no lifecycle scripts., The flagged bidi controls appear in Arabic country-name labels in a data table, consistent with localization data., The bundle loads GrapesJS assets for its page-builder component. - **Evidence against:** The local-storage wipe is triggered only after a user confirms the canvas-clear action., No install-time lifecycle script is declared in package.json., The bidi controls occur in localized country labels rather than concealed executable code. ## Affected versions and remediation This report applies to @inchurch/matcha-components@22.40.3. - Review the evidence and your use of @inchurch/matcha-components@22.40.3 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.
