8.8 (High) - CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
Summary
The Fancy Product Designer plugin for WordPress is vulnerable to unauthorized modification of site options due to a missing capability check on the fpd_update_options function in versions up to, and including, 4.6.9. This makes it possible for authenticated attackers with subscriber-level permissions to modify site options, including setting the default role to administrator which can allow privilege escalation.
