Xmlbuilder is a versatile Node.js library designed for programmatically constructing XML documents. Versions 4.1.0 and 4.2.0 share a common foundation, both relying on lodash (version ^3.5.0) as a dependency and offering similar development tools like coffee-script, mocha, coffee-coverage, istanbul, and coveralls for testing and code coverage. Both versions are licensed under the MIT license and maintained by Ozgur Ozcitak.
The most notable difference lies in their release dates: version 4.1.0 was released on November 11, 2015, while version 4.2.0 followed shortly after on December 16, 2015. This approximately month-long gap suggests that version 4.2.0 likely incorporates bug fixes, performance enhancements, or minor feature additions that were implemented following the release of 4.1.0.
For developers choosing between these versions, 4.2.0 is the preferred choice, as it represents the more recent and presumably improved iteration. While the specific changes between the two versions aren't detailed in the provided metadata, the newer release generally indicates a more stable and refined experience. Developers interested in creating XML structures within Node.js environments should find xmlbuilder easy to integrate and use. The library's consistent dependency on lodash and use of common testing tools highlights its stability and commitment to quality. To ensure optimal performance, consult the project's repository for detailed changelogs and any specific considerations for upgrading from earlier versions.
All the vulnerabilities related to the version 4.2.0 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.
Prototype Pollution in lodash
Versions of lodash prior to 4.17.19 are vulnerable to Prototype Pollution. The functions pick, set, setWith, update, updateWith, and zipObjectDeep allow a malicious user to modify the prototype of Object if the property identifiers are user-supplied. Being affected by this issue requires manipulating objects based on user-provided property values or arrays.
This vulnerability causes the addition or modification of an existing property that will exist on all objects and may lead to Denial of Service or Code Execution under specific circumstances.
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.
