At a glance

CVE-2026-18366 is a high-severity Improper Privilege Management vulnerability in the Events Manager WordPress plugin, affecting versions <= 7.4.0. It carries a CVSS score of 7.3 (reachable over the network; low attack complexity). Exploitation requires no authentication. The issue is fixed in version 7.4.1; sites on affected versions should update now. Disclosed August 2026, reported by Jakub Herman.

Vulnerability Overview

The Events Manager plugin for WordPress is vulnerable to Privilege Escalation in versions up to, and including, 7.4.0. This is due to insufficient restriction on the capabilities a user may grant themselves. This makes it possible for unauthenticated attackers to elevate their privileges beyond those intended for their role.

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-269: Improper Privilege Management

Reaching this weakness in Events Manager <= 7.4.0 takes no account at all. Improper privilege management means the code lets an account end up with capabilities its role should not have.

It converts a low-privileged account into an administrative one, which makes every other restriction on the site irrelevant. For Events Manager the fix is 7.4.1: builds <= 7.4.0 are affected, anything from 7.4.1 onward is not.

Remediation

Update to version 7.4.1, 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: Events Manager 7.4.1 closes this, and updating the plugin is the step that ends it.
