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 a concrete arbitrary-file-write supply-chain vulnerability in an explicit user command, not an automatic install-time attack. No lifecycle hook or confirmed secret exfiltration was found. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 93.0% - **Started:** 2026-09-12T09:29:45.386Z - **Finished:** 2026-09-12T09:30:40.733Z - **Download time:** 507 ms - **Static scan time:** 464 ms - **AI review time:** 54375 ms - **Total time:** 55347 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:** Explicit scaffolding downloads a remote file map and writes paths from that map without containment checks. A compromised service can write outside the selected project directory. - **Trigger:** The user runs create-chemx or chemx init with a license key. - **Impact:** A remote service can overwrite accessible local files or place a staged payload outside the intended project. - **Evidence paths:** cli/license.js, cli/scaffold.js - **Review source:** ai\_review - **Reviewed:** 2026-09-12T09:30:40.733Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Unchecked remote file paths are joined to a local target and written. - **Rationale:** This is a concrete arbitrary-file-write supply-chain vulnerability in an explicit user command, not an automatic install-time attack. No lifecycle hook or confirmed secret exfiltration was found. - **Files touched:** \/\, src/chemical-x/\ - **Network endpoints:** https://chemicalx.xophz.com/api/starter-kit/download ### Review decision - **Verdict:** Suspicious - **Confidence:** 93.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Critical Vulnerability - **False-positive risk:** Low - **Evidence for warning:** The scaffold downloads a server-supplied file map and writes every supplied path without validating that it remains inside the chosen project directory., The same unchecked write loop is reachable through the init command, whose default target is inside the current project., The remote response can therefore overwrite or create files outside the intended target through traversal paths. - **Evidence against:** package.json has no preinstall, install, or postinstall hook., The download and writes occur only after an explicit create or init command and license flow., Git hooks, CI workflow setup, and GitHub discussion publishing are explicit interactive commands. ## Affected versions and remediation This report applies to create-chemx@26.9.12-272. - Review the evidence and your use of create-chemx@26.9.12-272 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.
