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:** Data Exfiltration - **Selected version:** 1.0.37785938227 - **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 source establishes a cross-origin vulnerability in the running local editor API, so this package warrants a warning. The behavior is not evidence of malicious package intent, and the flagged agent hits are benign editor-related code. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 93.0% - **Started:** 2026-10-19T18:18:45.192Z - **Finished:** 2026-10-19T18:20:57.432Z - **Download time:** 1533 ms - **Static scan time:** 15367 ms - **AI review time:** 115339 ms - **Total time:** 132240 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 API has a cross-origin exposure that can let a hostile webpage access project files while the editor server is running. - **Trigger:** A user runs the local editor server and visits a webpage from another origin. - **Impact:** A hostile page may read or modify files within the configured project directory through the user's browser. - **Evidence paths:** dist/chunks/chunk-7QJXNUVM.js, dist/chunks/chunk-C7VL3DX7.js, dist/index.js - **Review source:** ai\_review - **Reviewed:** 2026-10-19T18:20:57.432Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The app reflects arbitrary origins through CORS and exposes file read and write routes without authentication. - **Rationale:** The source establishes a cross-origin vulnerability in the running local editor API, so this package warrants a warning. The behavior is not evidence of malicious package intent, and the flagged agent hits are benign editor-related code. - **Network endpoints:** localhost:9100 ### Review decision - **Verdict:** Suspicious - **Confidence:** 93.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Critical Vulnerability - **False-positive risk:** Medium - **Evidence for warning:** The manifest identifies a local development editor and has no lifecycle script; it exports the editor API., The editor server uses a localhost host setting and a default port of 9100., The app reflects the requesting browser origin in CORS responses and permits cross-origin read and write methods., The file API reads project files and accepts writes; the Node adapter resolves requested paths under the configured source directory., The flagged .cursor reference detects an editor, while the other cursor hit styles Monaco editor cursors. - **Evidence against:** The scanner’s agent-configuration hits are editor detection and cursor styling, not agent settings changes; no install-time behavior was found. ## Affected versions and remediation This report applies to @zuplo/editor@1.0.37785938227. - Review the evidence and your use of @zuplo/editor@1.0.37785938227 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.
