- CVE-2026-104393, 7 Oct 2026
- Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in weDevs Happy Addons for Elementor happy-elementor-addons allows Stored XSS.This issue affects Happy Addons for Elementor: from n/a through 3.50.0. CVE record
- CVE-2026-85006, 23 Sep 2026
- The HappyAddons for Elementor WordPress plugin before 3.50.0 does not escape an icon value on one of its button widgets before outputting it inside an HTML attribute, allowing users with Contributor-level access and above to inject event-handler attributes that execute JavaScript in the browser of anyone who views the page, including higher-privileged users reviewing the content, even though such users do not hold the unfiltered_html capability. CVE record
- CVE-2026-2917, 11 Mar 2026
- The Happy Addons for Elementor plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 3.21.0 via the `ha_duplicate_thing` admin action handler. This is due to the `can_clone()` method only checking `current_user_can('edit_posts')` (a general capability) without performing object-level authorization such as `current_user_can('edit_post', $post_id)`, and the nonce being tied to the generic action name `ha_duplicate_thing` rather than to a specific post ID. This makes it possible for authenticated attackers, with Contributor-level access and above, to clone any published post, page, or custom post type by obtaining a valid clone nonce from their own posts and changing the `post_id` parameter to target other users' content. The clone operation copies the full post content, all post metadata (including potentially sensitive widget configurations and API tokens), and taxonomies into a new draft owned by the attacker. CVE record
- CVE-2026-2918, 11 Mar 2026
- The Happy Addons for Elementor plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 3.21.0 via the `ha_condition_update` AJAX action. This is due to the `validate_reqeust()` method using `current_user_can('edit_posts', $template_id)` instead of `current_user_can('edit_post', $template_id)` - failing to perform object-level authorization. Additionally, the `ha_get_current_condition` AJAX action lacks a capability check. This makes it possible for authenticated attackers, with Contributor-level access and above, to modify the display conditions of any published `ha_library` template. Because the `cond_to_html()` renderer outputs condition values into HTML attributes without proper escaping (using string concatenation instead of `esc_attr()`), an attacker can inject event handler attributes (e.g., `onmouseover`) that execute JavaScript when an administrator views the Template Conditions panel, resulting in Stored Cross-Site Scripting. CVE record
- CVE-2026-1210, 3 Feb 2026
- The Happy Addons for Elementor plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the '_elementor_data' meta field in all versions up to, and including, 3.20.7 due to insufficient input sanitization and output escaping.

- The Happy Addons for Elementor plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'ha_page_custom_js' parameter in all versions up to, and including, 3.20.3 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with Contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page, despite the intended role restriction of Custom JS to Administrators.
