Lodash version 1.3.0 arrived swiftly after its predecessor, 1.2.1, both iterations solidifying Lodash's position as a go-to utility library designed for JavaScript developers. Both share the same foundational principles: delivering consistency, enabling customization, optimizing performance, and providing a wealth of extra functionalities. The library remains licensed under the permissive MIT license, ensuring broad accessibility and usage rights. Maintained by John-David Dalton, Lodash continues to evolve from its central GitHub repository, offering developers a robust and reliable toolkit.
Delving deeper into version 1.3.0, while the core description remains consistent with 1.2.1, the release date indicates a very near release, suggesting any key difference will most probably be a fix or update of small importance. Potential refinements might involve subtle performance enhancements, bug fixes discovered post-1.2.1 release, or minor API tweaks. Developers considering an upgrade should review the changelog or diff between these versions on the GitHub repository to identify any specific modifications affecting their codebase, even though the new version was only released after a few seconds after. This rapid succession hints at a focused and iterative development process within the Lodash project, prioritizing stability and responsiveness to user feedback. Checking the specific changes is paramount before upgrading.
All the vulnerabilities related to the version 1.3.0 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.
