CVE-2026-2917 - Happy Addons For Elementor Plugin
CVE-2026-2917
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.

Potential Impact
Severity is MEDIUM (CVSS 5.4). Depending on deployment context, affected components may be exposed to unauthorized actions or data integrity risk.
Exploitability Assessment
Exploitability is assessed as High based on remote code execution potential.
Primary risk drivers: remote code execution potential
Mitigation Recommendations
Validate affected product versions, prioritize patching, and monitor references for vendor remediation guidance. If immediate patching is not possible, apply compensating controls and limit exposure of vulnerable surfaces.
Detection & Monitoring
Track authentication anomalies, unexpected file writes, and suspicious plugin API activity around affected components.
Business Impact Lens
Prioritize remediation where affected components process customer data, admin sessions, or Internet-exposed workflows.
