At a glance

CVE-2026-16056 is a medium-severity Missing Authorization vulnerability in the Contest Gallery WordPress plugin, affecting versions <= 30.0.6. It carries a CVSS score of 4.3 (reachable over the network; low attack complexity). The root cause is a missing authorization check on a reachable function. The issue is fixed in version 30.0.7; sites on affected versions should update now. Disclosed July 2026, reported by Meher Sudhakar Abbireddi.

Vulnerability Overview

The Contest Gallery plugin for WordPress is vulnerable to unauthorized access due to a missing capability check on a function in versions up to, and including, 30.0.6. This makes it possible for authenticated attackers, with subscriber-level access and above, to perform an unauthorized action.

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 <= 30.0.6 takes a caller who can reach the endpoint. 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 30.0.7: builds <= 30.0.6 are affected, anything from 30.0.7 onward is not.

Remediation

Update to version 30.0.7, 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 30.0.7 closes this, and updating the plugin is the step that ends it.
