At a glance

CVE-2024-8437 is a medium-severity Missing Authorization vulnerability in the WP Easy Gallery WordPress plugin, affecting versions <= 4.8.5. 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. No fixed release has been reported yet; treat installations running this software as exposed. Disclosed September 2024, reported by Lucio Sá.

Vulnerability Overview

The WP Easy Gallery – WordPress Gallery Plugin plugin for WordPress is vulnerable to unauthorized access due to a missing capability check on several functions hooked via AJAX like wpeg_settings and wpeg_add_gallery in all versions up to, and including, 4.8.5. This makes it possible for authenticated attackers, with subscriber-level access and above, to modify galleries.

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 WP Easy Gallery <= 4.8.5 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. No fixed build of this plugin is recorded for WP Easy Gallery yet, so installs running <= 4.8.5 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?

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