This vulnerability has a CVSS 3.1 base score of 8.7, rated HIGH. It can be exploited remotely over the network. No authentication or special privileges are required for exploitation.

Technical description

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.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
