Lodash-es is a popular JavaScript utility library providing modularized ES modules for optimized tree shaking and smaller bundle sizes. Version 4.14.2, released on August 8, 2016, succeeds version 4.14.1, which was released on July 29, 2016. Both versions maintain the same core functionality offering a comprehensive suite of tools for common programming tasks such as array manipulation, object handling, function binding, and more. Under the MIT license, lodash-es encourages both personal and commercial use. Developed by John-David Dalton, Lodash-es simplifies javascript development through increased modularity.
While the descriptions and core repository details remain consistent between versions 4.14.1 and 4.14.2, the key difference lies in the incremental improvements and bug fixes incorporated. The ~10 day gap suggests a minor release addressing specific issues, potential performance enhancements, or refinements identified in the previous version. Upgrading to 4.14.2 is generally recommended for developers leveraging lodash-es, as it likely provides a more stable and optimized experience. Developers utilizing lodash-es benefit from cherry-picked utilities needed without importing the whole library. The minimal bundle size makes it ideal for javascript projects ranging from simple web apps to large javascript projects.
All the vulnerabilities related to the version 4.14.2 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.
