MediaWiki Insecure Storage of Sensitive Information Vulnerability (CVE-2021-36127)

Description

The Special:GlobalUserRights page provided search results which, for a suppressed MediaWiki user, were different than for any other user, thus easily disclosing suppressed accounts (which are supposed to be completely hidden).
