There is no fixed version for RHEL:9 rhel9/ruby-30.

NVD Description

Note: Versions mentioned in the description apply only to the upstream rhel9/ruby-30 package and not the rhel9/ruby-30 package as distributed by RHEL. See How to fix? for RHEL:9 relevant fixed versions and status.

Rack is a modular Ruby web server interface. The Rack::Sendfile middleware logs unsanitised header values from the X-Sendfile-Type header. An attacker can exploit this by injecting escape sequences (such as newline characters) into the header, resulting in log injection. This vulnerability is fixed in 2.2.12, 3.0.13, and 3.1.11.
