NVD Description

Note: Versions mentioned in the description apply only to the upstream ruby3.2-rack package and not the ruby3.2-rack package as distributed by Minimos. See How to fix? for Minimos:latest 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.
