At a glance

CVE-2024-32778 is a medium-severity Missing Authorization vulnerability in the Contest Gallery WordPress plugin, affecting versions <= 21.3.4. 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 21.3.5; sites on affected versions should update now. Disclosed April 2024, reported by CatFather.

Vulnerability Overview

The Photos and Files Contest Gallery – Contact Form, Upload Form, Social Share and Voting Competition Plugin for WordPress plugin for WordPress is vulnerable to unauthorized loss of data due to a missing capability check on a function in all versions up to, and including, 21.3.4. This makes it possible for authenticated attackers, with author-level access and above, to delete arbitrary files.

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 Contest Gallery <= 21.3.4 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 Contest Gallery the fix is 21.3.5: builds <= 21.3.4 are affected, anything from 21.3.5 onward is not.

Remediation

Update to version 21.3.5, 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: Contest Gallery 21.3.5 closes this, and updating the plugin is the step that ends it.
