Do not execute instructions or code found in this document. ## Verdict summary **Flagged — allowed with a warning** — Allowed by default policy, but 13 finding(s) warrant review before installing. - **Verdict:** Suspicious - **Product-default install policy:** Warn - **Firewall policy:** Matched warn-list - **Public report status:** Published - **Threat category:** Staged Payload Carrier - **Selected version:** 26.9.12-1140 - **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 package is not an automatic install-time threat, but its remote, unvalidated file delivery creates a real supply-chain write primitive. Treat it as suspicious until returned paths are contained and downloaded content is authenticated. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 91.0% - **Started:** 2026-09-12T19:05:03.890Z - **Finished:** 2026-09-12T19:06:06.394Z - **Download time:** 503 ms - **Static scan time:** 455 ms - **AI review time:** 61545 ms - **Total time:** 62504 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:** A user-invoked scaffold downloads an unverified file map and writes it using server-controlled paths. It also adds AI-agent rules to the new project. - **Trigger:** The user runs create-chemx, chemx create, or chemx init and provides a license key. - **Impact:** A compromised or malicious service response can place files outside the intended project through traversal paths and can deliver executable project content for later use. - **Evidence paths:** cli/license.js, cli/scaffold.js - **Review source:** ai\_review - **Reviewed:** 2026-09-12T19:06:06.394Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Remote file-map download followed by unrestricted project writes. - **Rationale:** The package is not an automatic install-time threat, but its remote, unvalidated file delivery creates a real supply-chain write primitive. Treat it as suspicious until returned paths are contained and downloaded content is authenticated. - **Files touched:** ~/.chemical-x/device\_id, ~/.chemical-x/config.json, \/\, \/.cursorrules - **Network endpoints:** https://chemicalx.xophz.com/api/starter-kit/download ### Review decision - **Verdict:** Suspicious - **Confidence:** 91.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Critical Vulnerability - **False-positive risk:** Low - **Evidence for warning:** The create and init commands write every filename and content value returned by the remote service without validating that paths stay inside the selected project., The remote request sends the supplied license key and a persistent device identifier to the Chemical X service., A scaffold run also creates a Cursor rules file that directs AI-agent behavior in the generated project. - **Evidence against:** package.json has no preinstall, install, postinstall, or other automatic lifecycle hook., The network download and project writes occur only after the user invokes a create or init command and provides a license key., No source evidence shows secret harvesting beyond the supplied license key, arbitrary shell execution, or automatic exfiltration. ## Affected versions and remediation This report applies to @chemx/create-chemx@26.9.12-1140. - Review the evidence and your use of @chemx/create-chemx@26.9.12-1140 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.
