With a ~2 MB payload, this can significantly slow down the JSON parsing - even on a powerful MacBook, this can hang for about half a minute. This means for servers that parse JSON from untrusted sources, a remote attacker can cause significant disruption via extreme asymmetric resource consumption. Since the same hashing scheme is also used for many other V8 internals, e.g., Map keys, this has a wide attack surface.
