CVE-2026-12277 Frontend File Manager Plugin CVE debrief
The Frontend File Manager Plugin WordPress plugin through 23.6 has a vulnerability allowing unauthenticated users to delete arbitrary files on the server when guest upload mode is enabled. This can be leveraged toward a full site takeover by deleting critical files such as wp-config.php, which forces the site into its setup routine. The vulnerability is particularly concerning because it can be exploited without authentication, making it a high-risk issue for WordPress site administrators. Evidence of exploitation has not been confirmed, but defenders should verify the integrity of their site files and configurations. Additional review of server logs and monitoring for unauthorized file deletions is recommended. Limited details are available about the specific conditions and potential impact beyond the initial report.
