Machine-written summary

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

GHSA-qhwx-74w5-xhxq affects the npm package vm2 in versions >=3.9.6 and <3.11.7, fixed in 3.11.7. On Node.js 24 and newer, when an embedder explicitly allows the node:test builtin in NodeVM, sandboxed code can reach the host node:test module through a doubled prefix and pass attacker-controlled execArgv to run(), which can execute JavaScript in an unrestricted host process. The source says this allows full escape of the sandbox with the host user's permissions, so upgrade vm2 to 3.11.7 or later.
