At a glance

CVE-2025-15516 is a medium-severity Missing Authorization vulnerability in the All-in-One Video Gallery WordPress plugin, affecting versions 4.1.0 – 4.6.4. It carries a CVSS score of 4.3 (reachable over the network; low attack complexity). Exploitation requires an authenticated account at Subscriber level or above. The issue is fixed in version 4.7.1; sites on affected versions should update now. Disclosed January 2026, reported by kr0d.

Vulnerability Overview

The All-in-One Video Gallery plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the ajax_callback_store_user_meta() function in versions 4.1.0 to 4.6.4. This makes it possible for authenticated attackers, with Subscriber-level access and above, to update arbitrary string-based user meta keys for their own account.

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

All-in-One Video Gallery 4.1.0 – 4.6.4 carries this weakness at ajax_callback_store_user_meta(), and reaching it takes an account at Subscriber 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 All-in-One Video Gallery the fix is 4.7.1: builds 4.1.0 – 4.6.4 are affected, anything from 4.7.1 onward is not.

Remediation

Update to version 4.7.1, 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: All-in-One Video Gallery 4.7.1 closes this, and updating the plugin is the step that ends it.
