Lodash-es offers the popular Lodash utility library re-packaged as ES modules, enabling developers to leverage modern JavaScript module systems for leaner bundles and improved tree-shaking. Examining versions 4.13.1 and 4.13.0, the key difference lies within the patch version increment, indicating a minor update focused on bug fixes and potentially small enhancements rather than new features or breaking changes. Released on the same day, but a few hours apart, this points to a situation that v4.13.1 probably addresses something that was considered important or time-sensitive.
For developers using lodash-es, this means upgrading from 4.13.0 to 4.13.1 should be a relatively safe and straightforward process. While a detailed changelog would provide more specific information, the versioning suggests the update aims to improve stability and reliability without requiring significant code modifications. Lodash-es itself remains a valuable tool for modern JavaScript development, providing a rich set of functions for array manipulation, object handling, string processing, and more. Its ES module format allows developers to selectively import only the functions they need, reducing bundle sizes. Staying up-to-date with the latest patch versions, like 4.13.1, ensures access to the most stable and refined version of the library.
All the vulnerabilities related to the version 4.13.1 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.
