Lodash-es offers the popular Lodash utility library in a modular format for modern JavaScript development, specifically designed for use with ES modules. This allows developers to selectively import only the functions they need, resulting in smaller bundle sizes and improved application performance compared to using the full Lodash library.
Version 4.16.5 arrived on October 31, 2016, building upon the foundation of version 4.16.4, which was released earlier in the same month, October 6. While both versions share the same core functionality and MIT license, developers should consider the release dates when choosing a version. Version 4.16.5 likely includes bug fixes and minor performance improvements identified since the earlier release of version 4.16.4. It's a subtle difference, but staying up-to-date with the latest patch version ensures a more stable and reliable experience.
The key advantage of lodash-es over the traditional Lodash library is its modularity. By leveraging ES modules, developers gain fine-grained control over which Lodash functions are included in their projects, leading to optimized bundle sizes and faster loading times, crucial for web applications prioritizing performance. Both versions are valuable for any modern javascript developer. Remember to check the diffs from github to see specific changes.
All the vulnerabilities related to the version 4.16.5 of the package
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 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.
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.
