xml2js is a Node.js library designed for converting XML documents into JavaScript objects, simplifying data extraction and manipulation for developers working with XML-based APIs or file formats. Versions 0.1.4 and 0.1.5 share identical descriptions, dependencies (sax >=0.1.1), author information (maqr), and even release dates (2011-04-20T16:17:56.230Z). The core difference lies in their version numbers and corresponding distribution tarballs, reflecting potentially small bug fixes or internal improvements between the two stable releases.
Developers choosing between these versions would likely opt for the later version (0.1.5) as a general best practice, assuming it incorporates minor enhancements or refinements without introducing breaking changes. The library's strength lies in its simplicity and ease of integration, enabling developers to effortlessly transform complex XML structures into easily navigable JavaScript objects. The dependency on 'sax' suggests a streaming XML parser, potentially making xml2js efficient for handling large XML files, minimizing memory consumption compared to DOM-based parsers. Maqr is the author. The tarball provides the library. While the release date is the same, the important thing is that 0.1.5 is newer and is recommended.
All the vulnerabilities related to the version 0.1.5 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.
