Authenticated PHP object injection via unsafe AJAX deserialization
Published Sep 20, 2026 · Updated Sep 20, 2026
PHP object injection in Unlimited Elements For Elementor before 2.0.20 allows remote authenticated users to inject arbitrary PHP objects. The plugin's AJAX handler omits a capability check and deserializes attacker-controlled stored data into PHP objects. Subscriber access reaches the handler before 2.0.18, while versions 2.0.18 through 2.0.19 require editor access; consequences beyond object injection depend on an available gadget chain.
