MediaWiki before 1.19.24, 1.2x before 1.23.9, and 1.24.x before 1.24.2 allows remote attackers to bypass the SVG filtering and obtain sensitive user information via a mixed case @import in a style element in an SVG file, as demonstrated by "@imporT."

Cross-site scripting (XSS) vulnerability in the Html class in MediaWiki before 1.19.24, 1.2x before 1.23.9, and 1.24.x before 1.24.2 allows remote attackers to inject arbitrary web script or HTML via a LanguageConverter substitution string when using a language variant.
Incomplete blacklist vulnerability in MediaWiki before 1.19.24, 1.2x before 1.23.9, and 1.24.x before 1.24.2 allows remote attackers to inject arbitrary web script or HTML via an animated href XLink element.
Incomplete blacklist vulnerability in includes/upload/UploadBase.php in MediaWiki before 1.19.24, 1.2x before 1.23.9, and 1.24.x before 1.24.2 allows remote attackers to inject arbitrary web script or HTML via an application/xml MIME type for a nested SVG with a data: URI.
