At a glance

CVE-2026-11905 is a medium-severity Missing Authorization vulnerability in the Elementor Website Builder WordPress plugin, affecting versions <= 4.2.3. It carries a CVSS score of 4.3 (reachable over the network; low attack complexity). Exploitation requires an authenticated account at Contributor level or above. The issue is fixed in version 4.2.4; sites on affected versions should update now. Disclosed October 2026, reported by Or Benit.

Vulnerability Overview

The Elementor Website Builder – more than just a page builder plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 4.2.3 via the 'keys_conversion_map' parameter. This makes it possible for authenticated attackers, with contributor-level access and above, to extract the full post_content and plaintext post_password of private, draft, pending, and future posts belonging to any author, including Administrators and Editors.

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 interaction from a victim user.

CWE-862: Missing Authorization

Elementor Website Builder <= 4.2.3 carries this weakness at keys_conversion_map, and reaching it takes an account at Contributor level or above. 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 Elementor Website Builder the fix is 4.2.4: builds <= 4.2.3 are affected, anything from 4.2.4 onward is not.

Remediation

Update to version 4.2.4, 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: Elementor Website Builder 4.2.4 closes this, and updating the plugin is the step that ends it.
