Recurring patterns

The bug types that recur here, drawn from past fixes, not open vulnerabilities.

Code Injection: User-controlled template options like 'pretty', 'doctype', 'templateName', and 'globals' are compiled directly into executable JavaScript. If these options are not rigorously validated against strict allowlists or regular expressions, attackers can execute arbitrary code during compilation.
