Chemical X Protocol: Private drop-in architecture starter kit and capsule generator
AI Security Review
scanned 1mo ago · by lpm-firewall-aiThe package is not install-time malware, but its explicit scaffolding flow trusts a remote server to define arbitrary files and does not prevent path traversal. That creates a concrete unresolved supply-chain and filesystem-write risk.
Static reason
No blocking static signals were detected.; previous stored version diff introduced dangerous source
Trigger
User runs a create, scaffold, or init CLI command and supplies or uses a cached license key.
Impact
A compromised or malicious service response could overwrite files outside the intended project or stage code in the user's workspace.
Mechanism
Remote file-map download followed by unchecked filesystem writes.
AI rationale
The package is not install-time malware, but its explicit scaffolding flow trusts a remote server to define arbitrary files and does not prevent path traversal. That creates a concrete unresolved supply-chain and filesystem-write risk.

Decision evidence
public snapshotAI called this Suspicious at 91.0% confidence as Dangerous Capability with low false-positive risk.
Evidence for warning
- The scaffold command downloads a server-controlled file map using the supplied license key and device identifier.
- Downloaded entries are written directly under the target directory without validating relative paths, allowing a response to place arbitrary project files.
- The package has no npm lifecycle hook, so this behavior requires an explicit CLI scaffold or init action.
Evidence against
- package.json defines bin commands and ordinary scripts but no preinstall, install, or postinstall hook.
- The network request and file writes are reached from explicit scaffolding commands, not package import or installation.
