Xmlbuilder is a popular Node.js library designed for programmatically generating XML documents. Version 2.5.2, released on February 16, 2015, builds upon the foundation of its predecessor, version 2.5.1, which was released a week earlier, on February 9, 2015. Both versions share the same core functionality, providing developers with a fluent and intuitive API for creating XML structures. They are both licensed under the MIT license and maintained by Ozgur Ozcitak. The underlying code repository is hosted on GitHub, making it easy for developers to contribute and report issues.
The primary difference between the two versions lies in their dependency on the Lodash utility library. Version 2.5.1 relies on Lodash version 3.1.0, whereas version 2.5.2 upgrades this dependency to version 3.2.0. While seemingly minor, this Lodash upgrade likely includes bug fixes, performance improvements, or new utility functions that enhance the overall stability and efficiency of xmlbuilder. For developers, this means that upgrading to version 2.5.2 offers the potential for a more polished and reliable experience, especially if their XML generation tasks heavily rely on Lodash's functionalities through xmlbuilder. Both versions support CoffeeScript for development and Vows for testing. Developers should consider the Lodash upgrade when adopting either version in their projects.
All the vulnerabilities related to the version 2.5.2 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.
