Lodash version 0.6.0 builds upon the solid foundation established by version 0.5.2, continuing its mission as a high-performance drop-in replacement for Underscore.js. Both versions offer developers a robust utility belt of functions designed to simplify common JavaScript tasks, from array manipulation and object operations to function binding and templating. The core value proposition remains consistent: enhanced performance, bug fixes, and a richer feature set compared to its predecessor, Underscore.js.
The key difference lies in the improvements and refinements introduced in version 0.6.0. While the specific bug fixes and performance enhancements are not detailed in the provided data, developers can anticipate a more stable and efficient library experience. Lodash aims to provide developers more tools and better performance to help them save time and effort in their javascript workloads, so every new version will try to improve on the previous one. Jumping from version 0.5.2 to 0.6.0 means leveraging accumulated improvements. For developers seeking a reliable and performant utility library, Lodash 0.6.0 presents a worthwhile upgrade, ensuring they benefit from the latest advancements and refinements within the Lodash ecosystem. The author, John-David Dalton, remains a constant, guaranteeing a consistent development philosophy focused on quality and performance. Always check the changelog to see specific improvements.
All the vulnerabilities related to the version 0.6.0 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.
