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. Source inspection found a cross-origin request proxy on the local editor server that accepts caller-selected destinations and exposes their responses. This is a concrete security risk, though the reviewed source does not establish malicious intent. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 91.0% - **Started:** 2026-10-22T00:30:31.403Z - **Finished:** 2026-10-22T00:32:14.258Z - **Download time:** 1281 ms - **Static scan time:** 15320 ms - **AI review time:** 86253 ms - **Total time:** 102855 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 local editor exposes a cross-origin request proxy that can reach caller-selected HTTP services and return their responses. - **Trigger:** A developer runs the local editor while visiting a site that submits a cross-origin request to its test API. - **Impact:** A hostile site may use the developer’s browser to make requests through the local server and read responses from services reachable by that server. - **Evidence paths:** package.json, dist/chunks/chunk-C7VL3DX7.js, dist/chunks/chunk-7QJXNUVM.js, dist/index.js - **Review source:** ai\_review - **Reviewed:** 2026-10-22T00:32:14.258Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The app reflects the request origin, accepts broad cross-origin headers, and forwards caller-supplied HTTP or HTTPS requests from the server. - **Rationale:** Source inspection found a cross-origin request proxy on the local editor server that accepts caller-selected destinations and exposes their responses. This is a concrete security risk, though the reviewed source does not establish malicious intent. - **Files touched:** package.json, dist/chunks/chunk-C7VL3DX7.js, dist/chunks/chunk-7QJXNUVM.js, dist/index.js - **Network endpoints:** localhost ### Review decision - **Verdict:** Suspicious - **Confidence:** 91.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Critical Vulnerability - **False-positive risk:** Medium - **Evidence for warning:** The package exports a Node runtime entry that starts the local editor server., The server defaults to localhost and binds its listener using that host setting., The editor app reflects request origins and allows broad cross-origin methods and headers., The test API accepts caller-supplied URLs, methods, and headers; its URL check only requires HTTP or HTTPS., The test proxy forwards the supplied request from the server and returns the upstream response body., The test route is mounted at the editor API’s test endpoint. - **Evidence against:** The proxy is part of the editor’s local test-request feature and the server defaults to localhost., No install-time script or package-controlled remote destination was identified. ## Affected versions and remediation This report applies to @zuplo/editor@1.0.39699278507. - Review the evidence and your use of @zuplo/editor@1.0.39699278507 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.
