CVE-2026-5193: Elementor Privilege Escalation Vulnerability

CVE-2026-5193 Overview

CVE-2026-5193 is a privilege escalation vulnerability in the Essential Addons for Elementor plugin for WordPress. The flaw affects all versions up to and including 6.5.13. The vulnerability stems from insufficient role validation in the register_user function, which only blocks assignment of the administrator role. Authenticated attackers with author-level access or higher can create new user accounts assigned elevated privileges such as editor. This weakness is classified under CWE-269: Improper Privilege Management.

Critical Impact

Authenticated users with author-level access can create new accounts with elevated roles, expanding their foothold on affected WordPress sites and enabling further compromise of site content and configuration.

Affected Products

• Essential Addons for Elementor – Popular Elementor Templates & Widgets plugin for WordPress
• All versions up to and including 6.5.13
• WordPress sites running the vulnerable plugin with open registration through Elementor forms

Technical Details for CVE-2026-5193

Vulnerability Analysis

The vulnerability resides in the register_user function inside includes/Traits/Login_Registration.php. The function implements role validation by checking only whether the requested role equals administrator. Any other role value passes validation and is accepted by the registration handler. An authenticated user with author-level access or higher can invoke the registration flow and supply a role parameter such as editor. The plugin then creates a new WordPress account with the requested elevated role. Because the editor role grants control over all posts and pages on the site, the attacker gains the ability to modify or delete content belonging to other users.

Root Cause

The root cause is an incomplete denylist in role validation logic. The plugin blocks a single high-privilege role rather than enforcing an allowlist of permitted roles. This design pattern fails whenever new privileged roles exist outside the blocked set. The corresponding fix is published in WordPress Plugin Changeset 3499726.

Attack Vector

Exploitation requires network access and at least author-level authentication on the target WordPress site. The attacker submits a crafted registration request through the plugin's registration handler, specifying a role value other than administrator. The plugin processes the request and creates the elevated account. No user interaction from a victim is required. Refer to the Wordfence Vulnerability Report for additional technical context.

Detection Methods for CVE-2026-5193

Indicators of Compromise

• New WordPress user accounts created with editor or other elevated roles that do not correspond to legitimate administrative actions.
• Unexpected POST requests to endpoints handled by the Essential Addons for Elementor Login_Registration trait.
• Audit log entries showing user creation events originating from author-level accounts.
• Modifications to posts and pages performed by newly created editor accounts shortly after registration.

Detection Strategies

• Review the WordPress users table for accounts with wp_capabilities containing editor, shop_manager, or other privileged roles created after the plugin was installed.
• Monitor web server logs for POST requests to admin-ajax endpoints invoking the plugin's registration action while authenticated as a non-administrator.
• Correlate account creation events with the originating session and authenticated user to identify accounts created by lower-privileged users.

Monitoring Recommendations

• Enable WordPress audit logging plugins to record user creation, role assignment, and authentication events.
• Forward web server and WordPress application logs to a centralized log analytics platform for retention and correlation.
• Alert on creation of any account assigned a role above subscriber outside change windows or established administrative workflows.

How to Mitigate CVE-2026-5193

Immediate Actions Required

• Update Essential Addons for Elementor to a version later than 6.5.13 that includes the fix from changeset 3499726.
• Audit existing WordPress accounts and remove or downgrade any unauthorized users with elevated roles.
• Review author-level and contributor-level accounts for signs of compromise and reset their credentials.

Patch Information

The vendor has published a fix in the plugin's source repository. Site administrators should apply the latest plugin update through the WordPress admin dashboard or by deploying the patched release from the official plugin directory. The patched code introduces stricter role validation in register_user.

Workarounds

• Disable the Essential Addons for Elementor login and registration widget until the plugin is updated.
• Restrict author-level and higher accounts to trusted users only, and enforce strong authentication including multi-factor authentication.
• Use a web application firewall rule to block registration requests that include a role parameter from authenticated non-administrator sessions.

# Example WordPress CLI commands to audit elevated accounts
wp user list --role=editor --fields=ID,user_login,user_email,user_registered
wp user list --role=administrator --fields=ID,user_login,user_email,user_registered
