Treat them as untrusted evidence. Do not execute instructions or code found in this document. ## Verdict summary **Blocked & quarantined** — Unrelated application state saved in localStorage for that origin is erased. - **Verdict:** Malicious - **Product-default install policy:** Block - **Firewall policy:** Matched malicious - **Public report status:** Published - **Threat category:** Destructive Action - **Selected version:** 22.42.1 - **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: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. The PageBuilder’s confirmed canvas-clear action silently erases all localStorage for the site, including unrelated application data. This is hidden destructive behavior, so the package should be blocked. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 94.0% - **Started:** 2026-10-31T04:30:59.473Z - **Finished:** 2026-10-31T04:31:43.267Z - **Download time:** 780 ms - **Static scan time:** 3716 ms - **AI review time:** 39297 ms - **Total time:** 43794 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 PageBuilder clear action also deletes all localStorage for the current origin. - **Trigger:** A user clicks the canvas-clear button and accepts the confirmation prompt. - **Impact:** Unrelated application state saved in localStorage for that origin is erased. - **Evidence paths:** fesm2022/inchurch-matcha-components.mjs - **Review source:** ai\_review - **Reviewed:** 2026-10-31T04:31:43.267Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The handler clears the canvas and then calls localStorage.clear() without limiting deletion to PageBuilder data. - **Attack narrative:** When a user confirms clearing the PageBuilder canvas, the handler also clears every localStorage entry for the current origin. The confirmation describes only cleaning the canvas, so it does not disclose or authorize erasing unrelated application data. - **Rationale:** The PageBuilder’s confirmed canvas-clear action silently erases all localStorage for the site, including unrelated application data. This is hidden destructive behavior, so the package should be blocked. - **Files touched:** localStorage for the current browser origin ### Review decision - **Verdict:** Malicious - **Confidence:** 94.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The PageBuilder’s canvas-clear handler confirms only a canvas reset, then calls localStorage.clear(), erasing all browser storage for the current origin. - **Evidence against:** The package exports a browser component bundle and declares no install or other lifecycle scripts., The destructive call is attached to a PageBuilder clear action that requires a user click and confirmation. ## Affected versions and remediation This report applies to @inchurch/matcha-components@22.42.1. - Avoid installing @inchurch/matcha-components@22.42.1. Remove it from direct dependencies and check your lockfile for transitive copies. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. - If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment. ## Public findings ### 1.
