CVE-2026-17540: Unknown File Manager

High severity, CVSS 8.8. EPSS: 0.4% chance of exploitation in the next 30 days.

The File Manager WordPress plugin before 6.9.1 does not properly authorise its file management commands, allowing any authenticated user, such as a subscriber, to read and delete arbitrary files under the WordPress installation directory, which could lead to the disclosure of the site's configuration secrets and to denial of service.
