Perl Taint在一般意义上是什么意思

我在Perl变量,模式等中读了很多关于Taint的内容,例如 docs：

$AUTOLOAD can Now be tainted

If you call a subroutine by a tainted name,and if it defers to an AUTOLOAD function,then $AUTOLOAD will be (correctly) tainted.

虽然谷歌的污点这个词的定义是：

DeFinitions of taint

verb

1. contaminate or pollute (something).
   “the air was tainted by fumes from the cars”
   synonyms: contaminate,pollute,adulterate,infect,blight,spoil,soil,ruin,destroy,befoul

noun

1. a trace of a bad or undesirable quality or substance.
   “the taint of corruption that adhered to the regime”
   synonyms: trace,touch,suggestion,hint,tinge,stain,blot,blemish,stigma,black mark,discredit,dishonor,disgrace,shame

那么Perl在Perl中的含义是什么？

解决方法

简而言之：任何来自外部且因此无法控制程序的数据都会被标记为受污染.系统或执行程序等敏感操作拒绝处理这些受污染的数据,您需要通过验证其内容来清除数据.正确使用可以防止命令注入和类似问题.
