design

This is a CLI utility, with no evident credential theft, exfiltration, persistence, or destructive behavior. It has significant HTML/script injection risks when processing untrusted component or Mermaid input, especially because preview CSP permits inline scripts and message-provided HTML is inserted without origin checks. The claimed sandboxing and CSP audit provide weaker protection than their labels imply. Severity is high for untrusted inputs, but the fragment does not establish malicious intent; external script host: cdn.jsdelivr.net.
