Description
The Seraphinite Post .DOCX Source plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the OnAdminApi_StateSet function, reachable through the 'seraph_pds_api' AJAX action, in all versions up to, and including, 2.16.15. This makes it possible for authenticated attackers, with Subscriber-level access and above, to add, change or remove arbitrary fields of the plugin's stored state. For example, they can remove the accepted EULA version, which puts the plugin into a non-functional mode until an administrator accepts the EULA again.
