CVE-2021-24879

Estado: ModificadaAlta (8.8)—

The SupportCandy WordPress plugin before 2.2.7 does not have CSRF check in the wpsc_tickets AJAX action, nor has any sanitisation or escaping in some of the filter fields which could allow attackers to make a logged in user having access to the ticket lists dashboard set an arbitrary filter (stored in their cookies) with an XSS payload in it.
