AI Security Review
scanned 2mo ago · by lpm-firewall-aiThis is concrete unconsented install-time mutation of a foreign project manifest, concealed in a detached delayed child process. No exfiltration was found, but the dependency-injection behavior independently warrants blocking.
Decision evidence
public snapshot- postinstall executes scripts/postinstall.cjs.
- Install hook targets the consuming project's package.json.
- It creates a missing consumer manifest without consent.
- A detached, hidden Node child waits then adds every declared peer dependency.
- The child is unref'd, allowing mutation after installation completes.
- No network endpoint, credential harvesting, or exfiltration code found.
- Published runtime modules are application-model/controller utilities; the confirmed hostile behavior is confined to postinstall.
