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." } ] }, "problemtype": { "problemtype_data": [ { "description": [ { "lang": "eng", "value": "Denial of Service (CWE-400)" } ] } ] }, "references": { "reference_data": [ { "name": "https://github.com/garycourt/uri-js/issues/12", "refsource": "MISC", "url": "https://github.com/garycourt/uri-js/issues/12" }, { "name": "https://nodesecurity.io/advisories/100", "refsource": "MISC", "url": "https://nodesecurity.io/advisories/100" } ] } }
