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:** Remote Code Execution - **Selected version:** 26.9.11-362 - **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. No automatic lifecycle behavior or confirmed credential exfiltration is present. However, the remote asset installer has a concrete path-traversal arbitrary-write risk during an explicit scaffold operation. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 91.0% - **Started:** 2026-09-11T06:31:15.795Z - **Finished:** 2026-09-11T06:32:09.688Z - **Download time:** 262 ms - **Static scan time:** 538 ms - **AI review time:** 53092 ms - **Total time:** 53893 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:** An explicit scaffolding run fetches a remote starter-kit file map and writes its paths without containment checks. A malicious or compromised service could use traversal paths to write outside the selected project. - **Trigger:** The user runs the create or scaffold CLI flow with a license key. - **Impact:** Potential arbitrary file overwrite and delivery of untrusted project files during scaffolding. - **Evidence paths:** cli/license.js, cli/scaffold.js - **Review source:** ai\_review - **Reviewed:** 2026-09-11T06:32:09.688Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Remote file-map download followed by unchecked path construction and file writes. - **Rationale:** No automatic lifecycle behavior or confirmed credential exfiltration is present. However, the remote asset installer has a concrete path-traversal arbitrary-write risk during an explicit scaffold operation. - **Files touched:** .chemical-x/config.json, .chemical-x/device\_id, .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 scaffold command downloads a server-provided file map and writes each supplied path without validating that it remains inside the target directory., The same explicit scaffold command creates a Cursor rules file in the newly created project., The package can persist a device identifier and supplied license key in the user's home configuration directory when its CLI is invoked. - **Evidence against:** package.json has no preinstall, install, or postinstall lifecycle hook., Network download and project writes occur only after the user runs a scaffold command and provides a license key., Git hooks and CI workflow writes are behind an interactive, explicit install command. ## Affected versions and remediation This report applies to create-chemx@26.9.11-362. - Review the evidence and your use of create-chemx@26.9.11-362 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.
