xml2js is a Node.js library designed for converting XML files into JavaScript objects, making it easier to work with XML data in JavaScript environments. Comparing versions 0.2.2 and 0.2.3, both share the same core functionality and description as a "Simple XML to JavaScript object converter." Key similarities include utilizing the "sax" dependency (version >=0.4.2) for parsing XML and providing the same repository URL on GitHub. Both versions also list the same author and their contact information.
The primary differences lie in the development dependencies and release dates. Version 0.2.3 updated zap to ">=0.2.5" from ">=0.2.4-3" and was released on January 29, 2013, while version 0.2.2 was released earlier, on November 15, 2012. This suggests that version 0.2.3 includes updates or fixes related to the "zap" development tool. For developers, this update implies potential improvements in testing or code analysis processes used during the library's development. While the core functionality remains consistent, developers might prefer the newer version (0.2.3) for its potentially more refined development environment and any associated bug fixes or performance enhancements, even if not explicitly documented in this data. For both versions, the identical repository URL allows you to easily trace back to the project on GitHub.
All the vulnerabilities related to the version 0.2.3 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.
