Bug report

PostCSS line return parsing error https://github.com/advisories/GHSA-7fh5-64p2-3v2j

Actual Behavior

It has dependency of "postcss": "^8.4.29", which is <8.4.31 according to https://github.com/advisories/GHSA-7fh5-64p2-3v2j

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.

Expected Behavior

Update the dependency of "postcss": "^8.4.29", to "^8.4.31"

How Do We Reproduce?

It already has a vulnerability CVE-2023-44270
