Packages
| Ecosystem | Package | Affected | Fixed in |
|---|---|---|---|
| RubyGems | actionpack | < 2.3.18 | 2.3.18 |
| RubyGems | actionpack | >= 3.0.0, < 3.1.12 | 3.1.12 |

Details
As written in the advisory (Markdown source, shown as plain text).
The sanitize helper 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 encoded `:` (colon) characters in URLs, which makes it easier for remote attackers to conduct cross-site scripting (XSS) attacks via a crafted scheme name, as demonstrated by including a `:` sequence.
