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 source establishes a meaningful cross-origin risk to project files while the consumer-started localhost server is running. This is a runtime vulnerability, not evidence of install-time malware, so warn rather than block. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 91.0% - **Started:** 2026-10-19T18:03:54.511Z - **Finished:** 2026-10-19T18:06:49.462Z - **Download time:** 1282 ms - **Static scan time:** 15266 ms - **AI review time:** 158403 ms - **Total time:** 174951 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:** When started, the local editor exposes project file read and write routes with permissive cross-origin access. A website able to reach the localhost listener may read or modify files within the project directory. - **Trigger:** A consumer starts the exported LocalEditorServer while a browser can access an untrusted website. - **Impact:** An untrusted website may access project contents, including sensitive files, or alter project files. The code does not establish automatic execution of altered files. - **Evidence paths:** dist/chunks/chunk-7QJXNUVM.js, dist/index.js, dist/chunks/chunk-C7VL3DX7.js, dist/chunks/chunk-FELEIEAB.js - **Review source:** ai\_review - **Reviewed:** 2026-10-19T18:06:49.462Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The app reflects request origins and allows GET and POST requests. Its filesystem API accepts caller-supplied paths for file reads and writes; path traversal is blocked and paths remain under the project directory. - **Rationale:** The source establishes a meaningful cross-origin risk to project files while the consumer-started localhost server is running. This is a runtime vulnerability, not evidence of install-time malware, so warn rather than block. - **Files touched:** dist/chunks/chunk-7QJXNUVM.js, dist/index.js, dist/chunks/chunk-C7VL3DX7.js, dist/chunks/chunk-FELEIEAB.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 LocalEditorServer that binds to the configured localhost host when started., The editor app reflects request origins in CORS, permits GET and POST, and mounts its API under /api., The filesystem API reads files and accepts writes at caller-supplied project paths., The Node filesystem adapter resolves paths under the project directory and rejects traversal segments., The flagged Cursor references are editor deep-link and cursor styling data., The manifest describes a local development editor; I found no lifecycle scripts. - **Evidence against:** This is a runtime exposure when a consumer starts the server, not install-time behavior., The filesystem adapter confines paths to the project directory, and the agent integration hints do not show agent configuration or plugin changes. ## Affected versions and remediation This report applies to @zuplo/editor@1.0.36668631705. - Review the evidence and your use of @zuplo/editor@1.0.36668631705 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.
