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.",

O reparo para GHSA-vwrp-x96c-mhwq bloqueia escritas de sandbox em intrínsecos do host clássicos, como Object.prototype, Array.prototype e Function.prototype, mas o código atual do sandbox em uma VM padrão ainda pode alcançar e mutar host Uint8Array.prototype, %TypedArray%.prototype e ArrayBuffer.prototype.",
