NVD Description

Note: Versions mentioned in the description apply only to the upstream mediawiki-doc package and not the mediawiki-doc package as distributed by RHEL. See How to fix? for RHEL:10 relevant fixed versions and status.

An issue was discovered in MediaWiki before 1.35.1. Missing users (accounts that don't exist) and hidden users (accounts that have been explicitly hidden due to being abusive, or similar) that the viewer cannot see are handled differently, exposing sensitive information about the hidden status to unprivileged viewers. This exists on various code paths.
