Lodash version 0.4.1 represents a minor but notable advancement over its predecessor, version 0.4.0, in the evolution of this popular JavaScript utility library. Both versions maintain the core promise of providing a drop-in replacement for Underscore.js, offering developers significant performance enhancements, crucial bug fixes, and a suite of additional features designed to streamline everyday JavaScript development. Created by John-David Dalton, Lodash aims to simplify complex tasks, promoting cleaner and more maintainable code.
The key difference lies in the subtleties between the releases. While both share identical descriptions, repository details (hosted on GitHub), and author information (including John-David Dalton's contribution), version 0.4.1 signifies an incremental improvement. This minor version bump typically indicates that the update includes a series of bug fixes and potentially some smaller performance tweaks that make the library incrementally better than its predecessor. For developers, this means a slightly more stable and refined experience when using Lodash within their projects.
Although precise specifics on the bug fixes of version that 0.4.1 provides over than the 0.4.0 aren’t specified in the data, the update highlights the ongoing commitment to quality and reliability of Lodash. Developers choosing between the two would likely benefit from opting for the newer version (0.4.1) expecting those subtle improvements and fixes to enhance performance and stability in real-world applications. This version offers a robust foundation and makes manipulating data in Javascript easier.
All the vulnerabilities related to the version 0.4.1 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.
Prototype Pollution in lodash
Versions of lodash before 4.17.5 are vulnerable to prototype pollution.
The vulnerable functions are 'defaultsDeep', 'merge', and 'mergeWith' which allow a malicious user to modify the prototype of Object via __proto__ causing the addition or modification of an existing property that will exist on all objects.
Update to version 4.17.5 or later.
Prototype Pollution in lodash
Versions of lodash before 4.17.11 are vulnerable to prototype pollution.
The vulnerable functions are 'defaultsDeep', 'merge', and 'mergeWith' which allow 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 4.17.11 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.
