PostCSS version 7.0.38 represents a minor patch release in the 7.x series of this widely-used tool for transforming CSS with JavaScript plugins. Developers will find that the core functionality remains consistent between versions 7.0.37 and 7.0.38, offering a stable foundation for their CSS processing workflows. The key dependencies nanocolors and source-map remain at compatible versions, ensuring continuity for projects already leveraging these libraries.
The primary distinction between the two versions lies in subtle internal adjustments. While the dependency versions are identical on the surface, the unpacked size of version 7.0.38 is marginally larger, hinting at possible internal refinements or bug fixes. Developers should refer to the official changelog on the PostCSS GitHub repository for a comprehensive breakdown of the specific changes implemented in this patch update. The release dates also highlight the very short time-span between the 2 releases, suggesting that version 7.0.38 may have been addressing a very quick fix deemed important by the maintainers. While this update is likely not a high priority for every developer, it is encouraged to update to the latest version to ensure the code is optimized as much as possible.
All the vulnerabilities related to the version 7.0.38 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.
