@chemx/create-chemx@26.9.12-272
Chemical X Protocol: Private drop-in architecture starter kit and capsule generator
AI Security Review
scanned 1mo ago · by lpm-firewall-aiThis is not an automatic npm lifecycle attack, but the explicit scaffolder provides an unverified remote payload-to-filesystem path with unchecked paths and writes an AI-agent control file. That is a concrete unresolved supply-chain capability warranting a warning.
Static reason
No blocking static signals were detected.; previous stored version diff introduced dangerous source
Trigger
A user runs create-chemx or chemx create/init with a license key.
Impact
A compromised or malicious template service could overwrite paths outside the intended project and place agent-control instructions.
Mechanism
Remote template download followed by unchecked filesystem writes and AI-agent rule creation.
AI rationale
This is not an automatic npm lifecycle attack, but the explicit scaffolder provides an unverified remote payload-to-filesystem path with unchecked paths and writes an AI-agent control file. That is a concrete unresolved supply-chain capability warranting a warning.

Decision evidence
public snapshotAI called this Suspicious at 90.0% confidence as Dangerous Capability with low false-positive risk.
Evidence for warning
- The user-invoked scaffolder downloads a server-supplied file map and writes every supplied path and content without validating paths or integrity.
- The same scaffolder creates a .cursorrules AI-agent instruction file in the generated project.
- The license module creates a home-directory configuration folder as soon as the CLI module is imported.
Evidence against
- package.json has no preinstall, install, postinstall, or other lifecycle hook.
- Network publication requires an explicit audit share action and uses a supplied GitHub token or the gh CLI.
- The hook and CI workflow installer is reachable only through explicit CLI commands and interactive choices.
