Version 0.5.6 of the csvtojson npm package represents a minor update over its predecessor, version 0.5.5, primarily focusing on internal improvements rather than introducing new features. Both versions share the core functionality of converting CSV data to JSON format, offering developers a tool with customizable parsing capabilities. Examining the metadata, the primary difference lies in the licensing and distribution details. Version 0.5.5 explicitly defines the MIT license with a URL pointing to the license file on GitHub, while version 0.5.6 simplifies this to just "MIT". This isn't a functional change but reflects a different way of expressing the license. The release dates reveal that version 0.5.6 was published on May 5th, 2016, a few days after version 0.5.5, which was released on May 2nd, 2016.
For developers considering using csvtojson, both versions offer a consistent set of dependencies and development dependencies, ensuring a similar development environment. These include essential libraries like async for asynchronous operations, along with a suite of Grunt-based tools for building, testing, and linting the code. The presence of tools like grunt-mocha-test and grunt-contrib-jshint indicate a focus on code quality and testing, reassuring developers about the library's reliability. The repository URL remains consistent across both versions, directing users to the GitHub repository for access to the source code, issue tracking, and contribution guidelines. The author information also remains the same, further pointing to the continuity between the two releases. Choose the latest v0.5.6.
All the vulnerabilities related to the version 0.5.6 of the package
CSVTOJSON has a prototype pollution vulnerability
The csvtojson package, a tool for converting CSV data to JSON with customizable parsing capabilities, contains a prototype pollution vulnerability in versions prior to 2.0.10. This issue arises due to insufficient sanitization of nested header names during the parsing process in the parser_jsonarray component. When processing CSV input containing specially crafted header fields that reference prototype chains (e.g., using proto syntax), the application may unintentionally modify properties of the base Object prototype. This vulnerability can lead to denial of service conditions or unexpected behavior in applications relying on unmodified prototype chains, particularly when untrusted CSV data is processed. The flaw does not require user interaction beyond providing a maliciously constructed CSV file.
