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.
