TL;DR

Underscored Node.js network builtins such as _http_client are not treated as dangerous and can be required when hosts allow broad builtin access. Sandbox code can open outbound HTTP connections and bypass network capability restrictions intended by NodeVM configuration. That enables SSRF-style access and capability bypass against isolated workloads. The patch extends the builtin denylist for underscored network modules.

Who does this affect?

You are affected if you are using a version that falls within the vulnerable range.
