Bucket is a MediaWiki extension to store and retrieve structured data on articles. Prior to 2.1.1, a stored XSS can be inserted into any Bucket table field that has a PAGE type, which will execute whenever a user views that table's corresponding Bucket namespace page. This vulnerability is fixed in 2.1.1.
