Last modified

CVE-2026-12277 is a high-severity vulnerability rated 8.7/10 on the CVSS scale. 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.. EPSS estimates a 0.15% chance of exploitation in the next 30 days.
