At a glance

CVE-2026-8380 is a medium-severity Missing Authorization vulnerability in the Frontend File Manager Plugin WordPress plugin, affecting versions <= 23.6. It carries a CVSS score of 4.3 (reachable over the network; low attack complexity). Exploitation requires an authenticated account at Author level or above. No fixed release has been reported yet; treat installations running this software as exposed. Disclosed June 2026, reported by Tiago Ferreira.

Vulnerability Overview

The Frontend File Manager Plugin plugin for WordPress is vulnerable to unauthorized access due to a missing capability check on a function in all versions up to, and including, 23.6. This makes it possible for authenticated attackers, with Author-level access and above, 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 interaction from a victim user.

CWE-862: Missing Authorization

Reaching this weakness in Frontend File Manager Plugin <= 23.6 takes an account at Author level or above. 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. No fixed build of this plugin is recorded for Frontend File Manager Plugin yet, so installs running <= 23.6 stay exposed until the vendor ships one.

Remediation

No known patch available. Please review the vulnerability's details in depth and employ mitigations based on your organization's risk tolerance. It may be best to uninstall the affected software and find a replacement.

How does WordSec protect against this?

Because it turns on account access, WordSec's login security is the relevant layer: role-based two-factor, captcha and brute-force limits raise the cost of getting the account this needs. No patched version is recorded yet, which is the case where a filtering layer matters most, because there is nothing to update to.
