GHSA-647f-g98j-qq25: vm2 (CVE-2026-92937)

Package	Ecosystem	Affected	Fixed in
vm2	npm	>=3.11.6, <3.11.7	3.11.7

Machine-written summary

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

GHSA-647f-g98j-qq25 affects the npm package vm2, versions 3.11.6 up to but not including 3.11.7. Untrusted code running in the sandbox can escape it when a host Promise rejects with an error carrying a property that references a host object, because the fix for GHSA-m283-3h24-438v does not cover registering the rejection handler through Function.prototype.call or apply. An attacker who can submit code to an affected deployment could execute arbitrary commands with the host process's privileges. Upgrade to vm2 3.11.7, which is the listed fixed version.
