Machine-written summary

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

vm2 versions 3.11.4 up to 3.11.7 are affected. A NodeVM configured with nesting enabled and an array-shaped require option bypasses its configuration check, so an attacker who can supply JavaScript that the NodeVM executes can reach the host vm2 module and run commands as the host Node.js process. Upgrade to vm2 3.11.7, which the source lists as the fixed version.
