Inquirer.js, a popular library for building interactive command-line interfaces, saw a notable update moving from version 0.3.5 to 0.4.0. While both versions offer the same core functionality – simplifying the creation of engaging CLI user experiences – several key differences emerge that are relevant for developers. Version 0.4.0 introduces an updated dependency on lodash, moving to version ~2.4.1 from ~1.2.1 in the previous release. This brings potential performance improvements and access to new utility functions offered by the newer lodash version.
through dependency was added which handles data transformation, potentially enhancing the library's internal stream processing capabilities. In terms of development dependencies, version 0.4.0 adopts a more current set of tools, including upgraded versions of chai, mocha, and sinon, and the addition of cmdify, mockery, grunt-mocha-test, and grunt-contrib-jshint. These changes collectively suggest an enhanced testing and linting environment, potentially leading to more robust and reliable code. The older proxyquire and grunt-simple-mocha dependencies were removed. Furthermore, considering the substantial gap in release dates – version 0.4.0 was released nearly two months after version 0.3.5 – this update likely incorporates bug fixes, performance enhancements, and potentially new features that streamline CLI development. Upgrading ensures developers benefit from the latest improvements and a smoother developer experience.
All the vulnerabilities related to the version 0.4.0 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.
