CVE-2021-21275 Information

Description

The MediaWiki \Report\ extension has a Cross-Site Request Forgery (CSRF) vulnerability. Before fixed version there was no protection against CSRF checks on Special:Report so requests to report a revision could be forged. The problem has been fixed in commit f828dc6 by making use of MediaWiki edit tokens.
