High impact if exploited, but EPSS currently rates exploitation as unlikely (0.51%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
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.
