今天凌晨，拼多多平台上出现巨大漏洞，用户可以任意领取100元无门槛抵用券，网传拼多多因此损失数额超过200亿元。
什么意思？领到优惠券的，不用四舍五入也=不用钱啊，大量的用户借此机会“薅羊毛”，用来充值大量Q币和话费。
今天中午，拼多多官方发出了关于“黑灰产通过平台优惠券漏洞不正当牟利”的声明，表示被黑灰产团伙盗取数千万元优惠券已报案，目前漏洞已经修复。
下面我们来看看相关报道。
Chinese online group discounter Pinduoduo Inc said on Sunday that an online collective exploited a loophole on its platform to “steal” tens of millions of yuan worth of discount vouchers.
In a statement on its official Weibo account, Pinduoduo said it immediately rectified the bug and reported the incident to police.
The fast-growing Nasdaq-listed online marketplace allows consumers to group together to get better discounts from merchants selling goods as varied as clothes, kitchenware and gadgets.
loophole & bug
○ loophole表示“（协议或法律的）漏洞，空子，破绽”，英文解释为“A loophole in the law is a small mistake which allows people to do something that would otherwise be illegal.”如：tax loopholes 税法的漏洞，a loophole in the law 法律上的一个漏洞，举个🌰：

○ 此处的bug是程序员最讨厌的东西之一，意思是“（计算机程序的）故障，毛病，缺陷，漏洞”，英文解释为“a fault in the system of instructions that operates a computer”。
bug本义是“小虫子”（a very small insect），也可以指“小病；轻微的传染病”（an illness that people catch very easily from each other but is not very serious），举个🌰：
I had a tummy/stomach bug last week.
上周我的肠胃出了点小毛病。
此外，bug还有“窃听器”的意思，英文怎么解释窃听器呢？A very small device fixed on to a phone or hidden in a room, that allows you to listen to what people are saying without them knowing.

vulnerability

vulnerability名词，其形容词性：vulnerable；vulnerability表示“易伤性；易损性；弱点；脆弱性”，此处可以直接解释为“漏洞”，英文解释为“the quality of being vulnerable (= able to be easily hurt, influenced, or attacked), or something that is vulnerable”，举个🌰：
As with any vulnerability analysis, we start by identifying the components and their external communication paths.
与任何漏洞分析一样，我们从确定组件及其外部通信路径开始。
