The npm package xml2js provides a simple and effective way to convert XML documents into JavaScript objects for easier manipulation and data access. Comparing version 0.2.4 with the immediately preceding stable version 0.2.3, the core functionality remains consistent, indicated by identical dependencies on the sax parser and development dependencies like zap, docco, and coffee-script. Both versions share the same description, author information, and repository details.
The primary difference lies in their release dates and distribution tarballs. Version 0.2.4 was released on February 10, 2013, while version 0.2.3 was released on January 29, 2013. Consequently, the tarball URLs in the dist section point to different files on the npm registry reflecting the respective version numbers.
For developers using xml2js, this highlights that the update from 0.2.3 to 0.2.4 likely involves bug fixes, minor enhancements, or dependency updates that don't fundamentally alter the API or core functionality. Developers should always refer to the package's changelog or commit history (available through the linked GitHub repository) for a comprehensive understanding of specific changes. Because the core dependencies remained constant, the changes should be relatively minor. It remains a practical tool for parsing XML structures in Node.js applications, especially scenarios requiring quick data extraction and manipulation.
All the vulnerabilities related to the version 0.2.4 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.
