CVE-2026-12277: CWE-73 External Control of File Name or Path in Frontend File Manager Plugin
The Frontend File Manager Plugin for WordPress up to version 23.6 contains a vulnerability that allows unauthenticated users to delete arbitrary files on the server when guest upload mode is enabled. This occurs because the plugin does not validate file paths derived from user input before deleting files. An attacker can delete critical files such as wp-config.php, which forces the site into its setup routine and can lead to a full site takeover.
AI Analysis
Technical Summary
CVE-2026-12277 is an external control of file name or path vulnerability (CWE-73) in the Frontend File Manager Plugin for WordPress through version 23.6. The plugin fails to validate user-supplied file paths before performing file deletion operations. When guest upload mode is enabled, this allows unauthenticated attackers to delete arbitrary files on the server, including sensitive configuration files like wp-config.php. Deletion of wp-config.php triggers the WordPress setup routine, which can be exploited to gain full control over the site.
Potential Impact
Unauthenticated attackers can delete arbitrary files on the server, including critical WordPress configuration files. This can disrupt site functionality and enable a full site takeover by forcing the site into its setup routine.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, it is recommended to disable guest upload mode to prevent unauthenticated file deletions.
