xml2js is a Node.js library designed for converting XML documents into JavaScript objects, making it easier to work with XML data within JavaScript applications. Examining versions 0.1.10 and 0.1.11 reveals only subtle changes, primarily in their release dates. Version 0.1.11 was released on October 1, 2011, while version 0.1.10 came out on August 31, 2011, indicating a relatively short timeframe between the two releases.
Both versions share the same core functionality, offering a "Simple XML to JavaScript object converter" as described. They also have identical dependencies, relying on the 'sax' parser for XML parsing, and the same developer dependencies, 'zap' and 'coffee-script', likely used for testing and development processes. Furthermore, the author, repository, and even the 'dist' information (pointing to the specific tarball on the npm registry) remain consistent.
For developers choosing between these specific versions, the practical difference is negligible. Both versions provide the same core XML conversion capabilities, with no apparent API changes or feature additions between them. Developers should choose the latest stable version if possible, or verify the changelog if they need more details between the versions. Both versions are compatible with the stated dependencies, suitable for projects requiring XML parsing functionality when the javascript object format is preferred.
All the vulnerabilities related to the version 0.1.11 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.
