Name of the Vulnerable Software and Affected Versions: MediaWiki extension Short Description versions 4.0.0

Description: The issue arises from the lack of proper sanitization of short descriptions before they are inserted as HTML, allowing any user to insert arbitrary HTML into the DOM by editing a page. This can lead to HTML injection.

Recommendations: For version 4.0.0, update to version 4.0.1 to patch this security flaw. As a temporary workaround, consider restricting the ability to edit pages until the update is applied.
