Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

The vm2 npm package, versions before 3.12.1, contains a sandbox escape in NodeVM because its DANGEROUS_BUILTINS denylist does not block child_process. An attacker who controls code running in a NodeVM sandbox configured with builtin:['*'] or with child_process explicitly allowed can load child_process and run arbitrary commands on the host system. Upgrade vm2 to version 3.12.1 or later.
