- Severity: CVSS 8.7 (High), CISA-ADP
- Vector: CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:C/C:N/I:H/A:H
- CISA SSVC: exploitation=none, automatable=no, technicalImpact=total

## Affected

- Unknown Frontend File Manager Plugin: through 23.6

## 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.
