At a glance
CVE-2026-14229 is a medium-severity Missing Authorization vulnerability in the ECS WordPress plugin, affecting versions <= 4.3.7. 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 4.3.8; sites on affected versions should update now. Disclosed August 2026, reported by Jashid Sany.
Vulnerability Overview
The ECS plugin for WordPress is vulnerable to unauthorized access in versions up to, and including, 4.3.7. This is due to missing visibility checks on the theme_id and post_id parameters in the wp_ajax_nopriv_ecsload handler before loading and returning Elementor document data. This makes it possible for unauthenticated attackers to access the content of private or password-protected Elementor documents by sending a crafted request to the ecsload AJAX endpoint.
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
Reaching this weakness in ECS <= 4.3.7 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 ECS the fix is 4.3.8: builds <= 4.3.7 are affected, anything from 4.3.8 onward is not.
Remediation
Update to version 4.3.8, 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: ECS 4.3.8 closes this, and updating the plugin is the step that ends it.
