The xml2js package offers a straightforward solution for converting XML documents into JavaScript objects, facilitating easier manipulation and data extraction within JavaScript environments. Versions 0.2.0 and 0.2.1 share a common foundation, both described as "Simple XML to JavaScript object converter" and leveraging the 'sax' parser with a version requirement of ">=0.1.1" for XML parsing. Both include identical development dependencies: 'zap' (version ">=0.2.4-2"), 'docco' (version ">=0.3.0"), and 'coffee-script' (version ">=1.0.1"), suggesting a consistent development and documentation workflow. The repository, author, and general structure remain the same. The key difference lies in the version number and their respective release dates. Version 0.2.0 was released on September 5, 2012, while version 0.2.1 followed on November 13, 2012. This indicates that version 0.2.1 likely contains bug fixes, performance enhancements, or minor feature additions compared to 0.2.0. For developers, choosing the latest stable version, 0.2.1, is generally advisable to benefit from any improvements and fixes implemented since the earlier release. Both offer a simple interface for converting XML into a JavaScript object and are suitable for projects needing to process XML data.
All the vulnerabilities related to the version 0.2.1 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.
