xml2js is a popular Node.js library that simplifies XML parsing into JavaScript objects. Versions 0.4.7 and 0.4.8 share a common foundation, offering developers a straightforward way to convert XML data for easy manipulation in their applications. Both versions rely on the sax parser and xmlbuilder for core functionality, ensuring reliable XML handling. Available on GitHub, the library is actively maintained and provides tools for developers to efficiently process XML feeds, configuration files, or data exchanges.
Examining the differences, the jump from version 0.4.7 to 0.4.8 mainly involves internal updates and potentially bug fixes reflected in the release timing. While the core dependencies remain identical, the releaseDate discrepancy points to improvements or patches made in the latter version. Developers should consider this when choosing a version, as 0.4.8 benefits from the most recent refinements. For those already using xml2js, upgrading to 0.4.8 is generally recommended to leverage any stability or performance enhancements implemented by the author, Marek Kubica. Both versions maintain the same set of development dependencies utilized for testing and documentation. If you need to process XML data in your Node.js project xml2js offers a solid solution.
All the vulnerabilities related to the version 0.4.8 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.
