CVE-2026-47139: Bypass Node Internal Modules Filter
Filtering Node.js builtin modules by ignoring 'internal/' does not sufficiently block all internal modules. Undocumented underscored modules like `_http_client` and `_http_server` bypass this filter and expose low-level network primitives. To securely restrict builtins, ensure underscored modules are also excluded (e.g., `!s.startsWith('_')`).
