How to fix?

Upgrade Debian:12 rails to version 2:6.0.3.7+dfsg-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 actionpack ruby gem (a framework for handling and responding to web requests in Rails) before 6.0.3.7, 6.1.3.2 suffers from a possible denial of service vulnerability in the Mime type parser of Action Dispatch. Carefully crafted Accept headers can cause the mime type parser in Action Dispatch to do catastrophic backtracking in the regular expression engine.
