CVE-2024-47782

Cross-site Scripting (XSS) in Special:WikiDiscover when displaying wiki information in WikiDiscover

State: Published
Severity: 7.6 High
Published: Oct 7, 2024
Updated: Oct 8, 2024
Reserved: Sep 30, 2024

Description

WikiDiscover is an extension designed for use with a CreateWiki managed farm to display wikis. Special:WikiDiscover is a special page that lists all wikis on the wiki farm. However, the special page does not make any effort to escape the wiki name or description. Therefore, if a wiki sets its name and/or description to an XSS payload, the XSS will execute whenever the wiki is shown on Special:WikiDiscover. This issue has been patched with commit `2ce846dd93` and all users are advised to apply that patch. User unable to upgrade should block access to `Special:WikiDiscover`.
