Insecure Direct Object Reference in Happy Addons for Elementor Plugin by WordPress

CVE-2026-2918

What is CVE-2026-2918?

The Happy Addons for Elementor plugin for WordPress is susceptible to an Insecure Direct Object Reference due to improper authorization in the validate_request() method. This results in authenticated users with Contributor-level access being able to alter the display conditions of published ha_library templates. Additionally, the AJAX action ha_get_current_condition does not perform necessary capability checks. The vulnerability is further exacerbated by the cond_to_html() renderer, which outputs condition values into HTML attributes without proper escaping. This oversight permits attackers to inject event handler attributes, potentially leading to Stored Cross-Site Scripting (XSS) attacks when an administrator accesses the Template Conditions panel.
