GHSA-3vgf-8m4q-q4qr: vm2: Default VM can mutate host TypedArray and ArrayBuffer intrinsics after the host-prototype pollution fix
Filed UTCSource GTH ↗
vm2's current host-intrinsic prototype protection is incomplete. The fix for GHSA-vwrp-x96c-mhwq blocks sandbox writes into classic host intrinsics such as Object.prototype, Array.prototype, and Function.prototype, but current head still lets sandbox code in a default VM reach and mutate host Uint8Array.prototype, %TypedArray%.prototype, and ArrayBuffer.prototype. After VM.run() returns, normal host typed-array and ArrayBuffer objects observe attacker-controlled properties and methods installed by the sandbox. …
