PostCSS 8.4.2 is a minor version update to the popular JavaScript tool for transforming CSS with plugins, succeeding version 8.4.1. Both versions, maintained under the MIT license, continue to offer developers a powerful and extensible way to manipulate CSS styles, enabling functionalities like autoprefixing, future CSS syntax usage, and custom transformations. The core dependencies remain consistent between the two releases, with both relying on nanoid for generating unique IDs, picocolors for colorful console output, and source-map-js for robust source map handling, ensuring smooth debugging experiences for developers.
While the description and functionalities remain unchanged, developers should note subtle differences. Specifically, PostCSS 8.4.2 shows a slight increase in the unpacked size of the package to 185528 bytes, compared to 185418 bytes in version 8.4.1. The file count remains consistent at 54 files. This suggests some incremental improvements, bug fixes, or minor feature additions within the new version. Furthermore, PostCSS 8.4.2 was released on November 26, 2021, a few days after its predecessor which was released on November 24, 2021. Upgrading to version 8.4.2 is generally recommended to benefit from the latest enhancements and ensure compatibility. Users can easily install PostCSS via npm using the respective tarball URLs provided. Developers are encouraged to explore the official PostCSS documentation and plugin ecosystem for powerful styling workflows.
All the vulnerabilities related to the version 8.4.2 of the package
PostCSS line return parsing error
An issue was discovered in PostCSS before 8.4.31. It affects linters using PostCSS to parse external Cascading Style Sheets (CSS). There may be \r discrepancies, as demonstrated by @font-face{ font:(\r/*);} in a rule.
This vulnerability affects linters using PostCSS to parse external untrusted CSS. An attacker can prepare CSS in such a way that it will contains parts parsed by PostCSS as a CSS comment. After processing by PostCSS, it will be included in the PostCSS output in CSS nodes (rules, properties) despite being originally included in a comment.
