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:** 26.9.11-631 - **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. This is an explicit-user-command remote payload writer with unchecked paths, creating a meaningful supply-chain risk. No lifecycle hook or source evidence shows automatic execution or confirmed theft. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 90.0% - **Started:** 2026-09-11T10:54:37.387Z - **Finished:** 2026-09-11T10:55:33.422Z - **Download time:** 251 ms - **Static scan time:** 482 ms - **AI review time:** 55301 ms - **Total time:** 56035 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 server-controlled file map and writes it into the chosen project location. Relative paths are not constrained, so a malicious response can escape that location. - **Trigger:** A user runs the create, scaffold, or init CLI command and supplies a license key. - **Impact:** A compromised or redirected service can overwrite project-adjacent files and stage code for later execution. - **Evidence paths:** cli/license.js, cli/scaffold.js - **Review source:** ai\_review - **Reviewed:** 2026-09-11T10:55:33.422Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Remote file-map download followed by unchecked filesystem writes. - **Rationale:** This is an explicit-user-command remote payload writer with unchecked paths, creating a meaningful supply-chain risk. No lifecycle hook or source evidence shows automatic execution or confirmed theft. - **Files touched:** cli/license.js, cli/scaffold.js - **Network endpoints:** https://chemicalx.xophz.com/api/starter-kit/download ### Review decision - **Verdict:** Suspicious - **Confidence:** 90.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The scaffold fetches a server-supplied file map using a license key and device identifier., Returned file names and contents are written without path validation or integrity verification., The endpoint can be changed through an environment variable. - **Evidence against:** package.json has no install lifecycle hook., The download and writes require an explicit scaffold or init command., GitHub token use is limited to the explicit audit-sharing path. ## Affected versions and remediation This report applies to chemx@26.9.11-631. - Review the evidence and your use of chemx@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.
