Authenticated PHP Object Injection in Unlimited Elements For Elementor Plugin

Publication date: 2026-09-20

Last updated on: 2026-09-20

Assigner: WPScan

Description
The Unlimited Elements For Elementor WordPress plugin before 2.0.20 does not perform a capability check on an AJAX action and deserializes attacker-controlled stored data through it, which makes it possible for authenticated attackers with subscriber-level access to inject arbitrary PHP objects. A partial fix in the 2.0.18 to 2.0.19 releases raised the privilege required to reach the vulnerable action to editor-level, and the issue was fully resolved in 2.0.20.

Executive Summary

This vulnerability is a PHP Object Injection flaw in the Unlimited Elements For Elementor WordPress plugin. It occurs because the plugin does not perform a capability check on an AJAX action and deserializes attacker-controlled stored data through it. This allows authenticated attackers with subscriber-level access to inject arbitrary PHP objects.

Detection Guidance

Check the installed version of the Unlimited Elements For Elementor plugin. If it is below 2.0.20, the system is vulnerable. Use WordPress admin panel or run: wp plugin list | grep unlimited-elements-for-elementor in WP-CLI.

Impact Analysis

An attacker could exploit this to inject malicious PHP objects, potentially leading to remote code execution, unauthorized data access, or complete site takeover. Even with a partial fix in versions 2.0.18 to 2.0.19, attackers with editor-level access could still exploit it until version 2.0.20 fully resolves the issue.

Compliance Impact

This vulnerability could lead to unauthorized data access or modification, violating GDPR's data protection requirements and HIPAA's security rules for protected health information. Organizations using vulnerable versions may face compliance breaches, legal penalties, and reputational damage.

Mitigation Strategies
