At a glance

This record tracks a medium-severity Cross-Site Request Forgery (CSRF) vulnerability in the Events Addon for Elementor WordPress plugin, affecting versions <= 2.1.2. It carries a CVSS score of 4.3 (reachable over the network; low attack complexity). Exploitation requires no authentication. The issue is fixed in version 2.1.3; sites on affected versions should update now. Disclosed November 2023.

Vulnerability Overview

The Events Addon for Elementor plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 2.1.2. This is due to missing nonce validation on the naevents_bw_settings_save_func(), naevents_bw_toggle_submit_func(), naevents_pro_settings_save_func(), naevents_pro_toggle_submit_func() and naevents_uw_settings_save_func() functions. This makes it possible for unauthenticated attackers to modify the plugin's settings via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.

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.

CWE-352: Cross-Site Request Forgery (CSRF)

Events Addon for Elementor <= 2.1.2 carries this weakness at naevents_bw_settings_save_func(), and reaching it takes a caller who can reach the endpoint. Cross-site request forgery abuses the fact that browsers attach a victim's cookies to any request, so a state-changing action that only checks who you are, not whether you meant to act, can be triggered from another site.

An attacker who gets a logged-in user to load a crafted page can perform that action as them, with the impact scaling to whatever the victim's role is allowed to do. For Events Addon for Elementor the fix is 2.1.3: builds <= 2.1.2 are affected, anything from 2.1.3 onward is not.

Remediation

Update to version 2.1.3, or a newer patched version

How does WordSec protect against this?

The attempt arrives as an ordinary request to Events Addon for Elementor: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: Events Addon for Elementor 2.1.3 closes this, and updating the plugin is the step that ends it.
