At a glance

CVE-2026-107649 is a medium-severity Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in the Events Made Easy WordPress plugin, affecting versions <= 3.2.22. It carries a CVSS score of 5.4 (reachable over the network). Exploitation requires no authentication. The issue is fixed in version 3.2.23; sites on affected versions should update now. Disclosed October 2026, reported by Jacek Sowiński (dzaku).

Vulnerability Overview

The Events Made Easy plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'event[location_name]' parameter in all versions up to, and including, 3.2.22 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This vulnerability is only exploitable when both the guest event submission feature (eme_fs[guest_submit]) and forced location creation (eme_fs[force_location_creation]) are explicitly enabled by a site administrator, as both settings default to off.

Technical Analysis

The vector marks this flaw as remotely reachable over the network, and no privileges on the target site, and no interaction from a victim user.

CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')

Events Made Easy <= 3.2.22 carries this weakness at event[location_name], and reaching it takes no account at all. Cross-site scripting happens when input from a request is written into a page without being escaped for the context it lands in, so the browser parses attacker-supplied text as markup or script.

Injected script runs with the privileges of whoever views the affected page, which is how these flaws turn into administrator session theft, silent account creation or persistent backdoors in page content. For Events Made Easy the fix is 3.2.23: builds <= 3.2.22 are affected, anything from 3.2.23 onward is not.

Remediation

Update to version 3.2.23, or a newer patched version

How does WordSec protect against this?

Requests carrying this pattern arrive without a session, so nothing upstream of the firewall gets a chance to reject them: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: Events Made Easy 3.2.23 closes this, and updating the plugin is the step that ends it.
