CVE-2026-92953 · vm2 3.11.0 through 3.11.7 Prototype Pollution via TypedArray
This page contains facts from public vulnerability sources. Check the original advisory before updating.
vm2 versions from 3.11.0 before 3.11.8 fail to protect host TypedArray and ArrayBuffer prototypes from sandbox mutation. Attackers can use prototype-walking primitives to reach and modify host Uint8Array.prototype, %TypedArray%.prototype, and ArrayBuffer.prototype, causing host-created typed arrays to observe attacker-controlled properties after VM.run() returns.
