xml2js is a Node.js library designed to simplify XML parsing into JavaScript objects. Comparing versions 0.1.7 and 0.1.8 reveals subtle but notable changes for developers. Both versions share the same core functionality, converting XML structures into easily accessible JavaScript data. Key dependencies include the "sax" parser, ensuring the library can efficiently handle XML input. Both versions also credit Marek Kubica as the author, reflecting the project's continued development under his guidance.
The primary difference lies in the development dependencies. Version 0.1.8 introduces "coffee-script" as a development dependency, indicating a potential shift or expansion in the codebase's development process, possibly for writing cleaner or more maintainable code. This addition likely supports internal tooling or testing rather than directly affecting how end-users interact with the parsed XML data. The "zap" dev dependency also sees an update, moving from version 0.2.0 in 0.1.7 to version 0.2.3 in 0.1.8, suggesting improvements or bug fixes in the testing or linting processes. Finally, the release date shows that version 0.1.8 was released on June 11, 2011, a few days after version 0.1.7, released on June 7, 2011.
For developers, upgrading from 0.1.7 to 0.1.8 promises potentially more robust internal tooling, which might lead to a more stable and reliable parsing experience, though the core parsing functionality remains largely consistent between the two versions. The introduction of coffee-script suggests a commitment to code quality and maintainability, which benefits the library in the long term.
All the vulnerabilities related to the version 0.1.8 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.
