Lodash-es is a popular JavaScript utility library offering a wide range of functions designed to simplify common programming tasks, particularly when working with arrays, objects, strings, and numbers. These two versions, 4.16.0 and 4.15.0, represent incremental improvements to this valuable tool.
While both share the same MIT license, repository origin, and author (John-David Dalton), the key difference lies in the version number and release date. Version 4.16.0 was released on September 19, 2016, subsequent to version 4.15.0, which was released on August 12, 2016. This indicates that 4.16.0 incorporates updates, bug fixes, and potentially new features built upon the foundation of 4.15.0.
For developers, this means that upgrading to 4.16.0 is generally recommended to leverage the latest improvements and address any known issues present in the older version. Before upgrading always consider checking the changelog for any breaking changes. Libraries like Lodash-es are crucial for modern JavaScript development because they offer modularity and ES module compatibility, allowing for tree-shaking and reduced bundle sizes, leading to more efficient and performant web applications. Choosing the most recent stable version ensures access to the most refined features and the benefit of community-driven enhancements. Developers should always consult the library's official documentation and release notes for a detailed list of changes between versions.
All the vulnerabilities related to the version 4.16.0 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.
