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. The package’s fallback is designed to obtain a same-version platform binary, but its hostname substring check does not bind NPM\_TOKEN to the intended registry. This creates conditional credential exposure risk, so warn without blocking publication. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 83.0% - **Started:** 2026-10-12T22:42:26.169Z - **Finished:** 2026-10-12T22:43:14.938Z - **Download time:** 500 ms - **Static scan time:** 125 ms - **AI review time:** 48143 ms - **Total time:** 48769 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:** The postinstall fallback can send NPM\_TOKEN to the tarball URL supplied by registry metadata when that URL’s hostname contains npmjs.org. - **Trigger:** The package is installed with lifecycle scripts enabled, its platform optional dependency is unavailable, and NPM\_TOKEN is set. - **Impact:** A crafted metadata URL with a spoofed hostname could expose the installer’s npm token; the source does not establish that such a URL is used in this package’s normal install path. - **Evidence paths:** package.json, install.js - **Review source:** ai\_review - **Reviewed:** 2026-10-12T22:43:14.938Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The installer uses a substring hostname check for the bearer token and requests the tarball URL obtained from package metadata without verifying that its host is the intended registry. - **Rationale:** The package’s fallback is designed to obtain a same-version platform binary, but its hostname substring check does not bind NPM\_TOKEN to the intended registry. This creates conditional credential exposure risk, so warn without blocking publication. - **Files touched:** install.js, bin/droid - **Network endpoints:** registry.npmjs.org ### Review decision - **Verdict:** Suspicious - **Confidence:** 83.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The package runs install.js automatically through its postinstall hook., The installer adds NPM\_TOKEN as a bearer token when the request hostname merely contains npmjs.org., The fallback fetches a package tarball URL from npm registry metadata, then requests that URL., The fallback runs only when the platform-specific optional dependency is unavailable., The installer writes the downloaded binary into its bin directory. - **Evidence against:** The fallback targets same-version @factory platform packages listed as optional dependencies., The installer’s first metadata request uses registry.npmjs.org. ## Affected versions and remediation This report applies to @factory/cli@0.239.0. - Review the evidence and your use of @factory/cli@0.239.0 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.
