At a glance

CVE-2024-0236 is a medium-severity Missing Authorization vulnerability in the EventON (Pro) - WordPress Virtual Event Calendar Plugin WordPress plugin, affecting versions <= 4.5.4. It carries a CVSS score of 5.3 (reachable over the network; low attack complexity). Exploitation requires no authentication. The issue is fixed in version 4.5.5; sites on affected versions should update now. Disclosed January 2024, reported by Erwan LR.

Vulnerability Overview

Multiple plugins and/or themes for WordPress are vulnerable to unauthorized access of data due to a missing capability check on the config_virtual_event() function in various versions. This makes it possible for unauthenticated attackers to retrieve the settings of arbitrary virtual events which can contain password data.

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

EventON (Pro) - WordPress Virtual Event Calendar Plugin <= 4.5.4 carries this weakness at config_virtual_event(), and reaching it takes a caller who can reach the endpoint. 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 EventON (Pro) - WordPress Virtual Event Calendar Plugin the fix is 4.5.5: builds <= 4.5.4 are affected, anything from 4.5.5 onward is not.

Remediation

Update to version 4.5.5, 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: EventON (Pro) - WordPress Virtual Event Calendar Plugin 4.5.5 closes this, and updating the plugin is the step that ends it.
