Lodash version 0.8.0 refines and extends the capabilities of its predecessor, version 0.7.0. Both versions serve as drop-in replacements for Underscore.js, offering developers enhanced performance, bug fixes, and a suite of additional features. However, the update from 0.7.0 to 0.8.0 signifies continued improvements and refinements within the library. Developers leveraging Lodash for its utility functions, particularly in data manipulation, functional programming, and general-purpose tasks, would find the upgrade beneficial.
The core value proposition of Lodash remains consistent across both versions: providing a robust and performant toolkit that simplifies common programming tasks. This includes enhanced methods for object manipulation, array processing, and function binding. While the overarching description remains the same, indicating a commitment to backward compatibility, the 0.8.0 release likely included internal optimizations and bug fixes, further solidifying Lodash's position as a reliable dependency.
The release date difference —version 0.8.0 released roughly three weeks after 0.7.0— suggests an active development cycle and a responsiveness to community feedback. For developers, this points to a library that is continuously being improved and refined. They should consult the changelog between the versions to understand the specific issues resolved and new features introduced. By upgrading to 0.8.0, developers could expect a more polished and performant experience, retaining the benefits of Lodash while benefiting from the latest enhancements.
All the vulnerabilities related to the version 0.8.0 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.
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.
