How to fix?

Upgrade Debian:12 rails to version 2.3.14.1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream rails package and not the rails package as distributed by Debian. See How to fix? for Debian:12 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.
