Vulnerability Overview

The Document Gallery plugin for WordPress is vulnerable to incorrect authorization in versions 4.1 to 5.1.1. This makes it possible for unauthenticated attackers to replace document thumbnails.

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.

CWE-284: Improper Access Control

Reaching this weakness in Document Gallery 4.1 – 5.1.1 takes no account at all. Improper access control means the code decides what a caller may do using something other than their actual permissions, so the decision can be wrong without any check appearing to be missing.

Whoever can shape the request decides the answer, so the protected action runs for callers the code never meant to allow. No fixed build of this plugin is recorded for Document Gallery yet, so installs running 4.1 – 5.1.1 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?

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. No patched version is recorded yet, which is the case where a filtering layer matters most, because there is nothing to update to.
