At a glance

CVE-2025-8357 is a medium-severity Missing Authorization vulnerability in the Media Library Assistant WordPress plugin, affecting versions <= 3.27. 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 3.28; sites on affected versions should update now. Disclosed August 2025, reported by wesley (wcraft).

Vulnerability Overview

The Media Library Assistant plugin for WordPress is vulnerable to arbitrary file deletion in the /wp-content/uploads directory due to insufficient file path validation and user capability checking in the _process_mla_download_file function in all versions up to, and including, 3.27. This makes it possible for authenticated attackers, with Author-level access and above, to delete arbitrary files on the server from the /wp-content/uploads/ directory.

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 Media Library Assistant <= 3.27 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. For Media Library Assistant the fix is 3.28: builds <= 3.27 are affected, anything from 3.28 onward is not.

Remediation

Update to version 3.28, 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: Media Library Assistant 3.28 closes this, and updating the plugin is the step that ends it.
