CVE-2025-21612 Information

Description

TabberNeue is a MediaWiki extension that allows the wiki to create tabs. Prior to 2.7.2 TabberTransclude.php doesn’t escape the user-supplied page name when outputting so an XSS payload as the page name can be used here. This vulnerability is fixed in 2.7.2.
