Discussion

MediaWiki 'InfoAction.php' HTML Injection Vulnerability

MediaWiki is prone to a HTML-injection vulnerability because it fails to properly sanitize user-supplied input.

Attacker supplied HTML and script code would run in the context of the affected browser, potentially allowing the attacker to steal cookie-based authentication credentials or control how the site is rendered to the user. Other attacks are also possible.

MediaWiki prior 1.21.9 and 1.22.6 are vulnerable.
