Vulnerability from github – Published: 2026-05-05 06:31 – Updated: 2026-05-05 06:31

Details

The ElementsKit Elementor Addons plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the Live_Action::reset() function in all versions up to, and including, 3.8.2 The function is hooked to the WordPress init action and triggers when both post and action=elementor GET parameters are present, with no authentication or nonce verification. This makes it possible for unauthenticated attackers to overwrite the Elementor content (_elementor_data) of any elementskit_widget custom post type by visiting a specially crafted URL. The widget's custom designs, text, and configurations are permanently replaced with a blank template.

Severity

6.5 (Medium)
