Upstream source description

The Rank Math SEO WordPress plugin before 1.0.280 does not escape a stored redirection source value before outputting it in an administrative list view, allowing users who can manage redirections (Administrators by default) to store JavaScript that executes in the session of any user who later opens that view, including a Super Administrator on multisite.
