An issue was discovered in PostCSS before 8.4.31. The 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 included in a
comment.
