Lodash-es is a modern build of the popular Lodash library, specifically tailored for use with ES modules in JavaScript environments. This allows developers to leverage Lodash's extensive utility functions with the benefits of modularity, like smaller bundle sizes and improved tree-shaking capabilities. Examining versions 3.9.0 and 3.9.2 reveals subtle, yet important updates. While both maintain the core functionality and MIT license, the key distinction lies in the release date, indicating bug fixes and minor improvements. Version 3.9.2 was released approximately five days after 3.9.0, suggesting quick response from the maintainers to address any issues that arose in the initial release.
For developers, this highlights the active development and responsiveness of the Lodash team. Upgrading from 3.9.0 to 3.9.2 ensures you are using the most up-to-date and stable version available, benefiting from potentially resolved bugs that might affect application performance or stability. The library itself provides a wealth of array manipulation, object handling, and function utility tools, simplifying complex JavaScript tasks and improving code readability. By using lodash-es developers leverage the power of lodash but reduce their application bundle by taking only the needed utilities, improving performance. Always check for the newest patches or minor upgrades to keep code healthy and secure.
All the vulnerabilities related to the version 3.9.2 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.
Prototype Pollution in lodash
Versions of lodash prior to 4.17.19 are vulnerable to Prototype Pollution. The functions pick, set, setWith, update, updateWith, and zipObjectDeep allow a malicious user to modify the prototype of Object if the property identifiers are user-supplied. Being affected by this issue requires manipulating objects based on user-provided property values or arrays.
This vulnerability causes the addition or modification of an existing property that will exist on all objects and may lead to Denial of Service or Code Execution under specific circumstances.
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.
