CVE-2026-12277: Unknown Frontend File Manager Plugin

High severity, CVSS 8.7. EPSS: 0.4% chance of exploitation in the next 30 days.

The Frontend File Manager Plugin WordPress plugin through 23.6 does not validate a file path derived from user input before deleting the referenced file, allowing unauthenticated users to delete arbitrary files on the server (such as wp-config.php) when guest upload mode is enabled. Deleting wp-config.php forces the site into its setup routine, which can be leveraged toward a full site takeover.

Affected products
