CVE-2026-24605: X Addons Elementor Auth Bypass Flaw

CVE-2026-24605 is an authentication bypass vulnerability in X Addons for Elementor affecting versions up to 1.0.23. Attackers can exploit misconfigured access controls to gain unauthorized access. This article covers technical details, affected versions, impact assessment, and mitigation strategies.

CVE-2026-24605 Overview

CVE-2026-24605 is a Missing Authorization vulnerability [CWE-862] in the pencilwp X Addons for Elementor plugin (x-addons-elementor) for WordPress. The flaw stems from incorrectly configured access control on one or more plugin endpoints. Authenticated users with low privileges can invoke functionality intended for higher-privileged roles. The vulnerability affects all plugin versions up to and including 1.0.23.

Critical Impact
Authenticated attackers with low-level WordPress accounts can bypass authorization checks in the X Addons for Elementor plugin and access functionality that should be restricted, leading to limited disclosure of plugin-managed data.

Affected Products

pencilwp X Addons for Elementor (x-addons-elementor) WordPress plugin
All versions from initial release through 1.0.23
WordPress installations using vulnerable plugin builds

Technical Details for CVE-2026-24605

Vulnerability Analysis

The vulnerability is a Broken Access Control issue in the X Addons for Elementor plugin. The plugin exposes actions or endpoints without enforcing capability or role checks. An attacker authenticated as a low-privileged WordPress user, such as a Subscriber, can invoke these endpoints over the network. Successful exploitation results in limited unauthorized access to plugin-controlled functionality or information.

The attack is performed remotely over HTTP, requires low complexity, and needs no user interaction. Confidentiality impact is limited, while integrity and availability are unaffected. EPSS data indicates a low predicted exploitation probability at the time of publication.

Root Cause

The root cause is missing authorization logic in plugin request handlers, classified as [CWE-862]. Handlers do not validate the requesting user's WordPress capabilities (for example, current_user_can()) before executing sensitive operations. As a result, role-based access control is enforced inconsistently across the plugin's action handlers.

Attack Vector

An attacker first obtains any authenticated WordPress account on the target site. The attacker then sends crafted HTTP requests to the affected plugin endpoints, such as AJAX actions registered by the plugin. Because no capability check rejects the request, the plugin executes the action. The attacker retrieves data or triggers behavior reserved for higher-privileged users. See the Patchstack Vulnerability Advisory for advisory-level details.

Detection Methods for CVE-2026-24605

Indicators of Compromise

Unexpected admin-ajax.php or REST API requests from low-privileged accounts targeting x-addons-elementor actions.
WordPress audit log entries showing Subscriber or Contributor accounts triggering plugin actions that normally require Editor or Administrator roles.
Newly registered low-privilege accounts followed by repeated requests to plugin endpoints associated with x-addons-elementor.

Detection Strategies

Inventory WordPress sites and identify installations running x-addons-elementor version 1.0.23 or earlier.
Inspect web server access logs for requests to plugin-specific AJAX actions and correlate with the requesting user's role.
Alert on anomalous HTTP POST volumes to wp-admin/admin-ajax.php originating from non-admin sessions.

Monitoring Recommendations

Forward WordPress, PHP, and web server logs into a centralized analytics platform for correlation across sites.
Monitor for privilege-mismatch patterns where low-role cookies invoke administrative plugin actions.
Track plugin version inventory continuously and flag instances still running 1.0.23 or earlier.

How to Mitigate CVE-2026-24605

Immediate Actions Required

Update the X Addons for Elementor plugin to a version later than 1.0.23 once the vendor publishes a fix.
Audit existing WordPress user accounts and remove unused low-privilege accounts that could be abused.
Restrict new user registration on sites that do not require it to reduce the authenticated attack surface.

Patch Information

Review the Patchstack Vulnerability Advisory for the latest patched version guidance from pencilwp. Apply the vendor-supplied update across all WordPress instances that run the plugin. Confirm the active plugin version after deployment.

Workarounds

Temporarily deactivate the x-addons-elementor plugin until a patched release is installed.
Deploy a Web Application Firewall rule that blocks unauthenticated and low-privileged requests to plugin-specific AJAX actions.
Disable open user registration (Settings → General → Membership) to limit which accounts can reach the vulnerable endpoints.

bash

# Configuration example: disable user registration and confirm plugin version via WP-CLI
wp option update users_can_register 0
wp plugin get x-addons-elementor --field=version
wp plugin update x-addons-elementor
