Lodash versions 1.0.0 and 1.0.1 represent incremental updates to this popular JavaScript utility library, renowned for its consistency, customizability, and performance enhancements. Both versions, released on the same day (August 31, 2013), share the same core description, MIT license, and maintainer. Developers will find the same consistent API, ideal for streamlining common programming tasks like array manipulation, object handling, and function composition. The library aims to improve code readability and reduce boilerplate.
A primary difference lies in the releaseDate, indicating a slight temporal gap of approximately 5 minutes between releases. While seemingly insignificant, this suggests that version 1.0.1 likely addresses minor bug fixes or very subtle improvements discovered immediately after the initial 1.0.0 release. While detailed changelogs would be necessary for a comprehensive understanding of the exact changes, it is reasonable to assume that version 1.0.1 offers a slightly more refined and stable experience. Both versions are accessible via npm and share the same foundational characteristics that have made Lodash a dependable choice for JavaScript developers seeking robust utility functions, and its influence is still noticeable today. Version 1.0.1 would typically be recommended for new projects, but in most cases either one might be acceptable, depending on project requirements.
All the vulnerabilities related to the version 1.0.1 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.
