The installer discovers and writes package content into multiple AI-agent skill directories. - **Trigger:** npm installation, through the postinstall lifecycle hook. - **Impact:** It mutates foreign AI-agent control surfaces and makes package-provided instructions available to multiple installed agents without an explicit setup command. - **Evidence paths:** package.json, scripts/postinstall.js, dist/services/skill-installer.js - **Review source:** ai\_review - **Reviewed:** 2026-09-14T08:14:07.977Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Automatic broad AI-agent skill installation. - **Attack narrative:** Installing the package runs scripts/postinstall.js, which starts the CLI with skill install. That command enumerates installed AI tools and copies the bundled skill, manifest, and marker into their home-directory skill locations. This is automatic mutation of a broad, foreign AI-agent control surface rather than an explicit user setup action. - **Rationale:** The package has a concrete postinstall chain that writes package-controlled content into many unrelated AI-agent skill directories. This meets the policy for malicious install-hook abuse. - **Files touched:** scripts/postinstall.js, dist/index.js, skill/SKILL.md, skill/package.json, ~/.codex/skills/cbs-4px-merchant-cli, ~/.claude/skills/cbs-4px-merchant-cli, ~/.cursor/skills/cbs-4px-merchant-cli ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** Installation automatically runs the bundled skill installer., The installer targets many AI-agent home directories, including Codex, Claude Code, Cursor, and others., It copies bundled files and writes manifests into those agent skill directories without an explicit user command. - **Evidence against:** No runtime dependency selects another release of this package., The observed network code is for the merchant API, update registry, and signed-update checking; it is not needed to establish the install-time control-surface mutation. ## Affected versions and remediation This report applies to cbs-4px-merchant-cli@0.0.12. - Avoid installing cbs-4px-merchant-cli@0.0.12. Remove it from direct dependencies and check your lockfile for transitive copies. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. - If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment. ## Public findings ### 1.
