Lodash 3.0.1 emerges as a subtle refinement over its predecessor, Lodash 3.0.0, both iterations championing a modular approach to JavaScript utilities. Targeting developers seeking efficient and performant code, both versions embody the core tenets of Lodash: consistent cross-environment behavior, blazing-fast performance, and comprehensive unit test coverage. Key assets are the MIT license and the code residing within the official GitHub repository ensuring transparency.
The primary distinction lies in the release dates, with version 3.0.1 surfacing just days after 3.0.0, implying a quick patch or minor enhancement. Specifically, Lodash 3.0.1 arrived on January 30, 2015, building upon the foundation laid by Lodash 3.0.0 on January 26, 2015. While the provided data excerpts don't explicitly detail the code-level changes between these micro-versions, the rapid succession suggests potential bug fixes, performance tweaks, or minor API adjustments. These incremental updates enhance the robustness and reliability of the library.
Developers are advised to transition to the slightly newer version, 3.0.1, to leverage any potential improvements implemented post-3.0.0. To access both versions, developers can utilize the provided tarball download links from the npm registry or directly interact with the GitHub repository to examine the specific changes made between the releases. This enables users a direct review, empowering them to take care of any specific use-cases that may be impacted by changes.
All the vulnerabilities related to the version 3.0.1 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.
