mediawiki is vulnerable to Improper Access Control. This vulnerability occurs when a user tries to access MediaWiki from a server that is not trusted. If the server sends an X-Forwarded-For header with the IP address of a malicious user, MediaWiki will automatically block the user which can be exploited by an attacker to block legitimate users from accessing MediaWiki.
