REDAXO before 5.21.0 contains a reflected cross-site scripting vulnerability that allows authenticated attackers to inject scripts via the type parameter of the metainfo_default_fields_create API. Attackers can craft a link with a valid CSRF token and HTML payload that rex_view::message() renders unescaped, executing scripts in a victim's backend session.
