CVE-2024-3235 is a medium-severity Missing Authorization vulnerability in the Essential Grid Gallery WordPress Plugin WordPress plugin, affecting versions <= 3.1.1. It carries a CVSS score of 5.3 (reachable over the network; low attack complexity). Exploitation requires no authentication.

Vulnerability Overview
The Essential Grid Gallery WordPress Plugin plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 3.1.1 via the on_front_ajax_action() function. This makes it possible for unauthenticated attackers to view private and password protected posts that may have private or sensitive information.
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-862: Missing Authorization
Essential Grid Gallery WordPress Plugin <= 3.1.1 carries this weakness at on_front_ajax_action(), and reaching it takes no account at all. 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 Essential Grid Gallery WordPress Plugin the fix is 3.1.2: builds <= 3.1.1 are affected, anything from 3.1.2 onward is not.
Remediation
Update to version 3.1.2, or a newer patched version
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. None of that substitutes for the fix: Essential Grid Gallery WordPress Plugin 3.1.2 closes this, and updating the plugin is the step that ends it.
