NVD Description

Note: Versions mentioned in the description apply only to the upstream ruby:3.1/rubygem-mysql2-doc package and not the ruby:3.1/rubygem-mysql2-doc package as distributed by AlmaLinux. See How to fix? for AlmaLinux:8 relevant fixed versions and status.

In the URI gem before 1.0.3 for Ruby, the URI handling methods (URI.join, URI#merge, URI#+) have an inadvertent leakage of authentication credentials because userinfo is retained even after changing the host.
