One of these features is validating whether or not a supplied URL is valid or not. To do this, uri-js uses a regular expression, This regular expression is vulnerable to redos. This causes the program to hang and the CPU to idle at 100% usage while uri-js is trying to validate if the supplied URL is valid or not. To check if you're vulnerable, look for a call to `require(\"uri-js\").parse()` where a user is able to send their own input. This affects uri-js 2.1.1 and earlier."}, {"lang": "es", "value": "uri-js es un m\u00f3dulo que intenta implementar RFC 3986 completamente.
