Xml2js is a popular npm package designed for converting XML documents into JavaScript objects, making it easier to work with XML data within JavaScript environments. Comparing versions 0.4.13 and 0.4.15 reveals subtle differences, primarily concerning their release dates and potentially internal fixes. The core functionality, centered around the sax parser and xmlbuilder for XML construction, remains consistent. Both versions share the same dependencies, including sax (version >=0.6.0) and xmlbuilder (version >=2.4.6), indicating stability in the underlying parsing and building mechanisms. Developers upgrading from 0.4.13 to 0.4.15 can likely expect a seamless transition, as the API and core functionality haven't drastically changed.
The devDependencies section lists useful tools like nyc for coverage, zap for further testing, diff for comparison, docco for documentation, coveralls for coverage reporting, and coffee-script which are used in development. Both versions are MIT licensed and have the same author and repository. The most significant change is the releaseDate, with 0.4.15 being released on October 30, 2015, and 0.4.13 on October 14, 2015. This suggests that version 0.4.15 likely addresses bug fixes or minor enhancements identified since the previous release. For developers, the newer version is generally recommended, as it incorporates the latest improvements and potential stability fixes. Check the changelog of the library to identify the specific updates included in 0.4.15 .
All the vulnerabilities related to the version 0.4.15 of the package
xml2js is vulnerable to prototype pollution
