Treat them as untrusted evidence. 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:** Staged Payload Carrier - **Selected version:** 26.9.11-631 - **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 execution or self-dependency chain exists. However, explicit use of the CLI downloads unauthenticated-by-integrity content and writes unchecked server-selected paths, creating a concrete supply-chain risk. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 91.0% - **Started:** 2026-09-11T10:54:37.311Z - **Finished:** 2026-09-11T10:55:27.918Z - **Download time:** 506 ms - **Static scan time:** 502 ms - **AI review time:** 49598 ms - **Total time:** 50607 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 scaffold or init command downloads an unverified file map from the vendor service and writes its entries locally. Unvalidated relative paths can escape the intended project directory. - **Trigger:** User runs the create or init CLI flow and supplies a license key. - **Impact:** A compromised or malicious service response could overwrite files outside the selected project and add AI-agent instructions. - **Evidence paths:** cli/license.js, cli/scaffold.js - **Review source:** ai\_review - **Reviewed:** 2026-09-11T10:55:27.918Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Remote payload download followed by unchecked filesystem writes. - **Rationale:** No automatic lifecycle execution or self-dependency chain exists. However, explicit use of the CLI downloads unauthenticated-by-integrity content and writes unchecked server-selected paths, creating a concrete supply-chain risk. - **Files touched:** .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:** Unknown - **False-positive risk:** Medium - **Evidence for warning:** The scaffold fetches a server-supplied file map and trusts it as the installation payload., Returned file paths are joined and written without path validation, allowing traversal outside the chosen target directory., The scaffold also creates a Cursor rules file containing agent directives. - **Evidence against:** package.json has no preinstall, install, or postinstall lifecycle hook., Scaffolding and in-repository installation require an explicit CLI command and a supplied license key., GitHub-token network use is reached through the explicit audit sharing flow. ## Affected versions and remediation This report applies to @chemx/starter-kit@26.9.11-631. - Review the evidence and your use of @chemx/starter-kit@26.9.11-631 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.
