At a glance

CVE-2023-7306 is a high-severity Missing Authorization vulnerability in the Frontend File Manager Plugin WordPress plugin, affecting versions <= 21.5. It carries a CVSS score of 7.5 (reachable over the network; low attack complexity; high integrity impact). Exploitation requires no authentication. The issue is fixed in version 22.0; sites on affected versions should update now. Disclosed July 2025, reported by Matteo Leonelli.

Vulnerability Overview

The Frontend File Manager Plugin plugin for WordPress is vulnerable to unauthorized loss of data due to a missing capability check on the wpfm_delete_multiple_files() function in all versions up to, and including, 21.5. This makes it possible for unauthenticated attackers to delete arbitrary posts.

Technical Analysis

The vector marks this flaw as remotely reachable over the network, with low attack complexity — no special timing or configuration is needed, and no privileges on the target site, and no interaction from a victim user. A successful exploit has high impact on integrity.

CWE-862: Missing Authorization

Frontend File Manager Plugin <= 21.5 carries this weakness at wpfm_delete_multiple_files(), and reaching it takes no account at all. A missing authorization check means a function is reachable by anyone who can reach the endpoint, because the code never asks whether the caller is allowed to perform the action.

Any user who can reach the endpoint gets to run an action reserved for higher-privileged roles, from reading protected data to changing settings or content. For Frontend File Manager Plugin the fix is 22.0: builds <= 21.5 are affected, anything from 22.0 onward is not.

Remediation

Update to version 22.0, or a newer patched version

How does WordSec protect against this?

This one needs no account at all, which puts it outside what login hardening can reach; WordSec's login security narrows the account-level paths around it, and the firewall is what inspects the request itself. None of that substitutes for the fix: Frontend File Manager Plugin 22.0 closes this, and updating the plugin is the step that ends it.
