How to fix?

There is no fixed version for RHEL:10 rubygem-actionpack.

NVD Description

Note: Versions mentioned in the description apply only to the upstream rubygem-actionpack package and not the rubygem-actionpack package as distributed by RHEL. See How to fix? for RHEL:10 relevant fixed versions and status.

The sanitize_css method in lib/action_controller/vendor/html-scanner/html/sanitizer.rb in the Action Pack component in Ruby on Rails before 2.3.18, 3.0.x and 3.1.x before 3.1.12, and 3.2.x before 3.2.13 does not properly handle \n (newline) characters, which makes it easier for remote attackers to conduct cross-site scripting (XSS) attacks via crafted Cascading Style Sheets (CSS) token sequences.
