Descriptions

In the Simple 301 Redirects by BetterLinks WordPress plugin before 2.0.4, the lack of capability checks and insufficient nonce check on the AJAX actions, simple301redirects/admin/get_wildcard and simple301redirects/admin/wildcard, made it possible for authenticated users to retrieve and update the wildcard value for redirects.

En el plugin Simple 301 Redirects by BetterLinks WordPress, versiones anteriores a 2.0.4, una falta de comprobación de capacidad y la comprobación insuficiente de nonce en las acciones AJAX, simple301redirects/admin/get_wildcard y simple301redirects/admin/wildcard, hacían posible que los usuarios autenticados recuperaran y actualizaran el valor del comodín para las redireccionamientos
