Horizon Alert
Summary of the vulnerability and why it matters
A vulnerability in the Easy Elements for Elementor WordPress plugin allows unauthorized users to gain administrator privileges. This happens because the plugin improperly handles user registration data, letting attackers overwrite crucial user role settings. This is a significant concern for any site using this plugin that allows new user registrations.
- Unauthenticated users can become administrators.
- Site registration and a login widget must be enabled.
- Affects the Easy Elements for Elementor plugin.
Attack Path
How an attacker could exploit the issue
An unauthenticated attacker could exploit this flaw to gain administrator privileges on a WordPress site. This is achieved by exploiting the plugin's user registration function, which fails to properly sanitize user meta data. The attacker would need to register a new account and inject specific user meta to elevate their privileges to administrator.
- Requires user registration enabled.
- Targets public Login/Register widget.
- Uses AJAX to overwrite user capabilities.
Live Threat
Current exploitation, exposure, and threat context
This vulnerability in the Easy Elements for Elementor plugin allows unauthenticated attackers to gain administrator privileges by exploiting a flaw in the user registration process. While requiring specific site configurations such as enabled user registration and a public-facing Login/Register widget, these conditions are often met on WordPress sites intended for public interaction. Therefore, exploitation is plausible for attackers targeting such environments.
- Exploitation requires specific site setup.
- No known public exploits exist.
- Vendor has released a patched version.
Priority actions
Operational Fix
Recommended remediation, mitigation, and detection steps
Teams should prioritize identifying and blocking any traffic attempting to exploit the Easy Elements for Elementor plugin's privilege escalation vulnerability. If user registration is enabled and the Login/Register widget is publicly accessible, investigate affected WordPress sites immediately for unauthorized administrator accounts. Given the ease of exploitation and critical impact, consider taking vulnerable services offline if they cannot be immediately patched.
- Update plugin to a version that addresses the vulnerability.
- Block requests to `easyel_handle_register` AJAX endpoint.
- Monitor for new administrator accounts created without authorization.
