TIMELINE May 4 Reserved by GitHub_M May 13 Published (CNA: GitHub_M) Aug 6 EXPLOIT PUBLISHED — CVE-2026-44005 (patriksimek vm2). Public exploit reference added.
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.
