Severity
4.3 (Medium) - CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:L/A:N
Summary
The Single Post Exporter WordPress plugin through 1.1.1 does not have CSRF checks when saving its settings, which could allow attackers to make a logged in admin change them via a CSRF attack and give access to the export feature to any role such as subscriber. Subscriber users would then be able to export an arbitrary post/page (such as private and password protected) via a direct URL
