Xml2js is a widely-used npm package designed for straightforward conversion of XML documents into JavaScript objects, simplifying XML data handling within Node.js environments. Comparing versions 0.2.6 and 0.2.7 reveals subtle yet important updates beneficial to developers. The core functionalities remain consistent, offering a simple API for parsing XML. However, version 0.2.7 introduces an updated dependency on the sax parser, moving from version 0.4.2 to 0.5.2. This update likely brings performance improvements and potential bug fixes inherent in the newer sax version, enhancing the parsing reliability. Furthermore, the devDependencies have been slightly bumped. docco moved from version 0.3.0 to >=0.6.2, and coffee-script improved from version 1.5.0 to >=1.6.1. While these are development dependencies, they suggest improvements in the documentation generation and testing environments for xml2js itself, contributing to overall package stability. Released in May 2013, version 0.2.7 builds upon the foundation of its predecessor (released February 2013) by incorporating dependency upgrades. For developers, sticking to the latest stable version, 0.2.7 in this case, is generally advisable to leverage updated dependencies and potential improvements. Its clear dependency declaration and the established GitHub repository also signal a well-structured and maintained library, key factors when choosing a reliable XML parsing tool.
All the vulnerabilities related to the version 0.2.7 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.
