CVE-2026-62089 Overview
CVE-2026-62089 is a missing authorization vulnerability in the Pixar Labs Master Addons for Elementor WordPress plugin. The flaw affects all versions up to and including 3.2.2. It stems from insufficient authorization checks [CWE-862], allowing authenticated users with low privileges to abuse functionality reserved for higher-privileged roles. Successful exploitation can compromise data integrity and cause a high-impact availability loss on the affected WordPress site.
Critical Impact
Authenticated attackers with low-level privileges can perform actions outside their permitted scope, modifying plugin state and disrupting site availability without user interaction.
Affected Products
- Pixar Labs Master Addons for Elementor (WordPress plugin)
- All versions from initial release through 3.2.2
- WordPress installations using the Master Addons Elementor extension

Technical Details for CVE-2026-62089
Vulnerability Analysis
The vulnerability is a broken access control issue in Master Addons for Elementor. The plugin exposes functionality without verifying whether the requesting user holds the required WordPress capability. A subscriber-level account, which is the lowest authenticated role on most WordPress deployments, can invoke operations intended for editors or administrators.
The outcome is privilege abuse. Attackers can trigger state-changing actions in the plugin, alter configuration, or interrupt Elementor-rendered content. Because the vulnerability sits inside a widely deployed page-builder extension, exploitation directly affects site availability and integrity of published content.
Root Cause
The root cause is a missing capability check [CWE-862] on one or more plugin endpoints. WordPress plugins are expected to call current_user_can() or verify a nonce paired with a capability check before executing privileged logic. Master Addons for Elementor releases through 3.2.2 omit that check, so any authenticated session is treated as authorized.
Attack Vector
Exploitation occurs over the network against a WordPress site running the vulnerable plugin. The attacker needs an authenticated account, but only low privileges are required and no user interaction is involved. After authenticating, the attacker sends a crafted HTTP request to the exposed plugin action to trigger the unauthorized operation. Refer to the Patchstack Vulnerability Report for endpoint-level technical detail.
Detection Methods for CVE-2026-62089
Indicators of Compromise
- Unexpected admin-ajax.php or REST API requests targeting Master Addons actions from low-privilege user sessions
- Modifications to Elementor widget configuration or plugin options without corresponding administrator activity
- New or altered content, shortcodes, or templates created by non-editor accounts
- Site availability incidents or Elementor rendering failures correlated with subscriber-level logins
Detection Strategies
- Audit WordPress access logs for POST requests to plugin endpoints originating from accounts with subscriber or contributor roles
- Compare plugin option values in the wp_options table against known-good baselines
- Enable WordPress audit logging plugins to record capability checks and option changes
- Alert when low-privilege users trigger plugin AJAX actions that historically only administrators invoke
Monitoring Recommendations
- Forward WordPress and web server logs to a centralized analytics platform for role-versus-action correlation
- Monitor authentication activity for credential stuffing or bulk subscriber account creation preceding exploitation
- Track plugin version inventory across managed WordPress sites to flag installations still on 3.2.2 or earlier
How to Mitigate CVE-2026-62089
Immediate Actions Required
- Update Master Addons for Elementor to a version later than 3.2.2 once released by Pixar Labs
- Restrict user registration on WordPress sites where subscriber-level accounts are not required
- Audit existing low-privilege accounts and remove those that are inactive or unattributed
- Review plugin configuration and revert any unauthorized changes
Patch Information
At time of publication, remediation guidance is tracked in the Patchstack Vulnerability Report. Administrators should apply the vendor-supplied fix as soon as it is available and confirm the installed plugin version is greater than 3.2.2.
Workarounds
- Deactivate Master Addons for Elementor until a patched release is available if the plugin is not business-critical
- Deploy a Web Application Firewall (WAF) rule to block requests to vulnerable plugin endpoints from non-administrator sessions
- Disable open user registration by unchecking Anyone can register under WordPress General Settings
- Enforce multi-factor authentication for all WordPress accounts to reduce the risk of low-privilege account compromise
# Configuration example: disable open registration and verify plugin version via WP-CLI
wp option update users_can_register 0
wp plugin get master-addons --field=version
wp plugin deactivate master-addons
