Lodash-es is a popular JavaScript utility library offering a modern, tree-shakeable build optimised for ES module environments. Versions 3.5.0 and 3.6.0, both released on the same day, showcase the rapid iteration typical of open-source projects. While seemingly incremental, the jump to version 3.6.0 likely includes bug fixes, performance enhancements, and potentially new functionalities or subtle API modifications not clearly spelled out in the metadata. Developers should consult the project's changelog on GitHub to determine the precise differences.
For developers leveraging ES modules, lodash-es provides a significant advantage over the traditional Lodash build. By importing only the specific functions you need, such as lodash-es/map or lodash-es/filter, you can dramatically reduce your bundle size, leading to faster load times and improved application performance. Both versions fall under the MIT license, granting developers broad freedom in using and distributing the library. John-David Dalton, the author, is a well-known figure in the JavaScript community, which lends credibility and assurance to the library's quality. To leverage the library, use your preferred package manager and use npm install lodash-es@3.6.0 or npm install lodash-es@3.5.0 to install the desired version. Consider using the latest version unless there are specific reasons to pin to an older one. Always prioritize consulting official project resources and release notes to identify all specific changed and new functionalities.
All the vulnerabilities related to the version 3.6.0 of the package
Prototype Pollution in lodash
Versions of lodash before 4.17.12 are vulnerable to Prototype Pollution. The function defaultsDeep allows a malicious user to modify the prototype of Object via {constructor: {prototype: {...}}} causing the addition or modification of an existing property that will exist on all objects.
Update to version 4.17.12 or later.
Regular Expression Denial of Service (ReDoS) in lodash
lodash prior to 4.7.11 is affected by: CWE-400: Uncontrolled Resource Consumption. The impact is: Denial of service. The component is: Date handler. The attack vector is: Attacker provides very long strings, which the library attempts to match using a regular expression. The fixed version is: 4.7.11.
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.
