At a glance

CVE-2025-11510 is a medium-severity Improper Authorization vulnerability in the FileBird WordPress plugin, affecting versions <= 6.4.9. 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. The issue is fixed in version 6.5.0; sites on affected versions should update now. Disclosed October 2025, reported by kai.

Vulnerability Overview

The FileBird – WordPress Media Library Folders & File Manager plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the /filebird/v1/fb-wipe-clear-all-data function in all versions up to, and including, 6.4.9. This makes it possible for authenticated attackers, with author-level access and above, to reset all of the plugin's configuration data.

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-285: Improper Authorization

Reaching this weakness in FileBird <= 6.4.9 takes an account at Author level or above. Improper authorization means a permission check exists but does not cover the case being exercised, so a caller who is allowed to do one thing is allowed to do a neighbouring thing as well.

A lower-privileged account performs an action reserved for a higher one, which on a multi-author or membership site means an ordinary user reaching administrative behaviour. For FileBird the fix is 6.5.0: builds <= 6.4.9 are affected, anything from 6.5.0 onward is not.

Remediation

Update to version 6.5.0, or a newer patched version

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. None of that substitutes for the fix: FileBird 6.5.0 closes this, and updating the plugin is the step that ends it.
