Lodash version 0.8.2 represents a minor update over its predecessor, version 0.8.1, focusing primarily on refinements and bug fixes within this utility library. Both versions champion Lodash's core mission: providing a high-performance, feature-rich, and drop-in replacement for Underscore.js, empowering developers with versatile tools for common JavaScript tasks. Key functionality remains consistent, with both offering a comprehensive suite of functions for array manipulation, object handling, function binding, and more.
The shift from 0.8.1 to 0.8.2 likely introduced subtle performance improvements and addressed reported issues, enhancing overall stability and reliability for developers relying on Lodash in their projects. Developers considering these versions should prioritize 0.8.2 for its bug fixes that were not present in 0.8.1. This ensures a smoother development experience and reduces the risk of encountering unexpected behavior. Since that both versions are quite old (released in 2012), it's important to note that while version 0.8.2 is an improvement over 0.8.1, using a more recent version of Lodash is highly recommended for access to the latest features, bug fixes, and performance optimizations. The library has evolved significantly since these early releases, and newer versions offer a substantially more robust and efficient toolkit for modern JavaScript development.
All the vulnerabilities related to the version 0.8.2 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.
