Low risk4th percentile - higher than 4% of all known CVEs
Summary
The Frontend File Manager Plugin for WordPress up to version 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.
Risk Assessment
The risk for the organization includes complete loss of control over the WordPress site, as an attacker can delete critical configuration files and hijack the installation process, leading to full site takeover and potential data breach.
Recommendation
Immediately update the Frontend File Manager plugin to the latest available version; if not available, disable guest upload mode or temporarily deactivate the plugin until a patch is released.

See all- CVE-2026-16292Medium
The Frontend File Manager Plugin for WordPress up to version 23.6 lacks nonce validation on one of its file-metadata update actions. This allows a CSRF attack where an attacker can modify the metadata of a logged-in user's uploaded file and then download it. When guest uploads are enabled, the same action is reachable unauthenticated against any user's file.
