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 release has no lifecycle hook, so there is no automatic install-time attack. Its server-controlled, unchecked scaffold payload remains a concrete supply-chain risk that warrants a warning.
Static reason
No blocking static signals were detected.; previous stored version diff introduced dangerous source
Trigger
The user runs the create or init CLI command with a license key.
Impact
A compromised service could deliver unexpected files or use traversal paths to write outside the selected project.
Mechanism
Remote payload retrieval followed by unchecked project file writes.
AI rationale
This release has no lifecycle hook, so there is no automatic install-time attack. Its server-controlled, unchecked scaffold payload remains a concrete supply-chain risk that warrants a warning.

Decision evidence
public snapshotAI called this Suspicious at 91.0% confidence as Dangerous Capability with low false-positive risk.
Evidence for warning
- The scaffold downloads a server-controlled file map after license verification.
- Downloaded path names are not validated before files are written into the target project.
- The scaffold adds a Cursor rules file to each newly created project.
Evidence against
- package.json contains no install lifecycle hook.
- The download and project writes require an explicit create or init command.
