The xml2js package, designed for straightforward XML to JavaScript object conversion, saw a minor version bump from 0.1.1 to 0.1.2 on April 20, 2011. While seemingly incremental, such updates can hold subtle yet important changes for developers utilizing the library. Both versions share the same fundamental purpose: providing a simple means to parse XML data into JavaScript objects, a common task in web development and data processing scenarios.
The xml2js package, authored by maqr, aims to simplify the handling of XML data within JavaScript environments. Developers often encounter XML when interacting with APIs or legacy systems, and xml2js offers a convenient alternative to manual parsing. The common description highlights the package's core functionality – converting XML into a JavaScript object for simpler manipulation – making it easily searchable by developers needing this functionality. Given the identical release date and author information, it is likely that version 0.1.2 includes internal improvements, bug fixes, or minor adjustments to the parsing logic, without introducing significant new features that would warrant a more substantial version change. For developers, upgrading from 0.1.1 to 0.1.2 is recommended to take advantage of these enhancements, ensuring a smoother and potentially more reliable XML parsing experience. Developers should review the detailed changelog if available.
All the vulnerabilities related to the version 0.1.2 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.
