Lodash-es is a popular JavaScript utility library offering a comprehensive collection of functions designed to simplify common programming tasks. Versions 4.10.0 and 4.11.0 represent iterations within the project's evolution, providing developers with powerful tools for data manipulation, function handling, and more, all packaged as ES modules for modern JavaScript environments.
The update from version 4.10.0 to 4.11.0, released just two days later, signifies continued refinement and optimization of the library. While the core functionality remains consistent, developers can anticipate potential bug fixes and performance improvements implemented in the newer release. This iterative approach underscores the project's commitment to providing a stable and efficient utility belt for JavaScript developers.
For developers considering lodash-es, both versions offer a wealth of utilities, including array manipulation, object handling, string processing, and more. The ES module format ensures compatibility with modern JavaScript build tools and module bundlers, promoting efficient code organization and tree-shaking to reduce bundle sizes. Selecting the latest version, 4.11.0, grants access to the most recent enhancements and bug fixes, while remaining confident in the solid foundation established by its predecessor. The MIT license ensures the library can be used freely in a wide variety of projects.
All the vulnerabilities related to the version 4.11.0 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.
