css-loader version 4.1.1 is a patch release following closely after 4.1.0, both designed as CSS loader modules for Webpack. Examining the metadata reveals minimal differences, primarily in the distribution package details. Version 4.1.1 has a slightly larger unpacked size (108223 bytes) compared to 4.1.0 (107469 bytes), suggesting minor code adjustments or additions, alongside a newer release date.
For developers, the core functionality remains consistent across both versions, as the dependencies and devDependencies are identical. This includes crucial packages like postcss for CSS processing, loader-utils for Webpack loader utilities, and schema-utils for options validation. The peer dependency on webpack remains unchanged, allowing compatibility with Webpack versions 4.27.0 and above, as well as Webpack 5.
The key takeaway is that upgrading from 4.1.0 to 4.1.1 should be seamless, assuming no internal code relies on undocumented behavior. Given the nature of patch releases as bug fixes and minor improvements, upgrading to 4.1.1 is generally recommended to leverage the latest stability enhancements. Always consult the official changelog or release notes for detailed information on specific fixes or changes, even in patch versions. This ensures a smooth transition and helps developers understand any potential impact on their projects.
All the vulnerabilities related to the version 4.1.1 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.
