Cross-site request forgery (CSRF) vulnerability in WordPress Meta Data Filter & Taxonomies Filter versions prior to v.1.2.8 and versions prior to v.2.2.8 allows remote attackers to hijack the authentication of administrators via unspecified vectors.
The Meta Data and Taxonomies Filter WordPress plugin, in versions < 1.3.1, is affected by a reflected cross-site scripting vulnerability in the 'taxname' parameter of the mdfgettaxoptionsinwidget action, which can only be triggered by an authenticated user.
