## Description

The HappyAddons for Elementor plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the Lordicon, Icon Box and Info Box widgets' Lordicon animation URL (icon_cdn / icon_json) in versions 3.6.0 up to, and including, 3.51.0, due to insufficient validation of the user-supplied animation source URL, which may point to any external host. The bundled lord-icon player evaluates Lottie expressions found in the animation JSON. This makes it possible for authenticated attackers, with contributor-level access and above, to point the icon at an attacker-hosted animation file and run arbitrary web scripts in pages, which execute whenever a user opens an injected page.

Also published later by wordfence as CVE-2026-123473.
