Xml2js is a node.js library designed for converting xml files to javascript objects. It is a lightweight tool that empowers developers to easily parse xml data in their javascript applications. Version 0.4.4 and 0.4.3 are very similar, sharing the same core functionality and dependencies. Both versions depend on sax for parsing and xmlbuilder for xml construction which ensures consistency in handling xml data. The development dependencies also remain the same, using tools like zap, diff, docco, and coffee-script for testing, documentation and code maintainability.
The most noticeable difference between the two versions lies in the release date. Version 0.4.4 was released on May 28, 2014, while version 0.4.3 was released ten days before , on May 18, 2014. This suggest that version 0.4.4 likely contains bug fixes, performance improvements, or minor feature enhancements implemented after the release of version 0.4.3.
For developers using xml2js, upgrading from 0.4.3 to 0.4.4 is generally recommended. These incremental upgrades typically address any potential issues discovered in the previous version, leading to a more stable and reliable experience. Because the dependencies are the same, the upgrade effort should be minimal, while the potential benefits are stability and performance improvements. Both versions are readily available through npm, making installation straightforward. Developers can leverage xml2js to seamlessly integrate xml data into their node.js projects, streamlining data processing and manipulation for various applications.
All the vulnerabilities related to the version 0.4.4 of the package
xml2js is vulnerable to prototype pollution
xml2js versions before 0.5.0 allows an external attacker to edit or add new properties to an object. This is possible because the application does not properly validate incoming JSON keys, thus allowing the __proto__ property to be edited.
