CVE-2026-5193 — Privilege Escalation

title: Privilege Escalation via Essential Addons for Elementor User Registration — CVE-2026-5193
id: scw-2026-05-14-ai-1
status: experimental
level: high
description: |
  Detects attempts to exploit CVE-2026-5193 by targeting the 'register_user' function in the Essential Addons for Elementor plugin. This function, when improperly called via admin-ajax.php, allows authenticated users with author-level access to create new users with elevated privileges (e.g., editor) due to insufficient role validation. This rule specifically looks for the 'action=ea_elementor_register_user' parameter within the admin-ajax.php endpoint, indicating a potential exploitation attempt.
