Lodash-es is a modern JavaScript utility library offering a wide range of helpful functions for manipulating arrays, objects, strings, and more, designed for use in ES module environments. Examining versions 3.8.0 and 3.9.0, both versions share characteristics like being licensed under MIT, using the same repository on GitHub, and having John-David Dalton as author. The core description remains consistent, indicating a focus on providing a modern build of Lodash specifically tailored for ES module usage.
The most notable difference is the release date and version number. Version 3.9.0 was released on May 19, 2015, subsequent to version 3.8.0, which was released on May 1, 2015. This makes version 3.9.0 the newer release. The update might include bug fixes, performance improvements, or potentially new features.
Developers choosing between these versions should opt for 3.9.0 for latest functionality as it's the most up to date version. If migrating from 3.8.0, review the changes introduced in 3.9.0 to ensure compatibility as well. When incorporating lodash-es in projects, developers benefit from cleaner code, faster development, and greater code maintainability when compared to writing from scratch many common functions.
All the vulnerabilities related to the version 3.9.0 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.
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.
