  "details" : [ "vm2 is an open source vm/sandbox for Node.js. From 3.9.6 to 3.10.5, vm2's bridge exposes mutable proxies for real host-realm intrinsic prototypes and then forwards sandbox writes into the underlying host objects with otherReflectSet() and otherReflectDefineProperty(), which lets attacker-controlled JavaScript running in a default VM or inherited NodeVM mutate shared host Object.prototype, Array.prototype, and Function.prototype from inside the sandbox This vulnerability is fixed in 3.11.0.", "A flaw was found in vm2 3.9.6 through 3.10.5. The VM bridge exposes mutable proxies for host intrinsic prototypes and forwards sandbox writes via otherReflectSet/otherReflectDefineProperty, allowing mutation of host Object.prototype, Array.prototype, and Function.prototype from inside the sandbox. Fixed in 3.11.0." ],

A remote unauthenticated attacker who can run code in a default VM or NodeVM may modify shared host JavaScript prototypes and achieve arbitrary code execution. Fixed in vm2 3.11.0.",
