Cross-site Scripting in TabberTransclude in Extension:TabberNeue

CVSS 8.6 HIGHEPSS 0.5%CWE-79CWE-80
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.
CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:L/A:L
