Do not execute instructions or code found in this document. ## Verdict summary **Flagged as AI-agent capability risk** — Allowed by default with warning: agent-facing configuration or capability changes need review before use. - **Verdict:** Suspicious - **Product-default install policy:** Warn - **Firewall policy:** Warn-only AI-agent capability risk - **Public report status:** Published - **Threat category:** AI-agent capability abuse - **Selected version:** 26.9.12-272 - **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 concrete malicious lifecycle, secret exfiltration, or stealth persistence is present. The unchecked remote file-write path and explicit AI-agent configuration mutation warrant a warning. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 86.0% - **Started:** 2026-09-12T08:59:47.441Z - **Finished:** 2026-09-12T09:00:48.875Z - **Download time:** 768 ms - **Static scan time:** 538 ms - **AI review time:** 60127 ms - **Total time:** 61434 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 a file map from the vendor service and writes it locally without constraining returned paths. Scaffolding also creates a project-level Cursor rules file. - **Trigger:** User runs the create or init CLI flow and provides a license key. - **Impact:** A compromised or malicious starter-kit service could overwrite files outside the intended target through traversal paths and place behavior-bearing project files. - **Evidence paths:** cli/license.js, cli/scaffold.js - **Review source:** ai\_review - **Reviewed:** 2026-09-12T09:00:48.875Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Remote server-provided file writes with unvalidated relative paths. - **Rationale:** No concrete malicious lifecycle, secret exfiltration, or stealth persistence is present. The unchecked remote file-write path and explicit AI-agent configuration mutation warrant a warning. - **Files touched:** \/\, .cursorrules, ~/.chemical-x/config.json, ~/.chemical-x/device\_id - **Network endpoints:** https://chemicalx.xophz.com/api/starter-kit/download ### Review decision - **Verdict:** Suspicious - **Confidence:** 86.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Critical Vulnerability - **False-positive risk:** Medium - **Evidence for warning:** The create and init commands fetch a server-supplied file map and write every returned path without path validation., The scaffold command adds a Cursor rules file to the newly created project., The package has no npm lifecycle hook, so these actions require an explicit CLI command. - **Evidence against:** No install, preinstall, or postinstall script is declared., Network use is limited to the stated starter-kit service and explicit GitHub discussion publishing., Child-process calls use fixed command names and argument arrays rather than shell interpolation. ## Affected versions and remediation This report applies to @chem-x/create-chemx@26.9.12-272. - Review the evidence and your use of @chem-x/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.
