Deferred Deferred - Pending Action
Unauthenticated Data Modification in Royal Addons for Elementor

Publication date: 2026-05-02

Last updated on: 2026-05-05

Assigner: Wordfence

Description
The Royal Addons for Elementor plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the `wpr_update_form_action_meta` AJAX action in all versions up to, and including, 1.7.1056. The handler is registered on both `wp_ajax` and `wp_ajax_nopriv` hooks, making it accessible to unauthenticated users. Although a nonce is verified, the nonce (`wpr-addons-js`) is publicly exposed in frontend JavaScript via `WprConfig.nonce` on any page that loads Royal Addons widgets, rendering the protection ineffective. The endpoint also lacks any capability or ownership checks and directly calls `update_post_meta()` with user-controlled input on a whitelisted set of form action meta keys. This makes it possible for unauthenticated attackers to modify form action configuration metadata (email, submissions, Mailchimp, and webhook settings) on any post, potentially leading to webhook/email action tampering and data exfiltration via modified webhook URLs.

Executive Summary

The Royal Addons for Elementor plugin for WordPress has a vulnerability that allows unauthorized users to modify data. This happens because the plugin's AJAX action handler for updating form action metadata does not properly check user capabilities.

Although the plugin verifies a nonce, the nonce is publicly exposed in frontend JavaScript, making the protection ineffective. The AJAX endpoint is accessible to unauthenticated users and lacks ownership or capability checks, allowing attackers to change form action settings such as email, submissions, Mailchimp, and webhook configurations.

This means attackers can tamper with webhook or email actions and potentially exfiltrate data by modifying webhook URLs.

Compliance Impact

The vulnerability allows unauthenticated attackers to modify form action configuration metadata, including email, submissions, Mailchimp, and webhook settings. This could lead to tampering with webhook and email actions and potential data exfiltration via modified webhook URLs.

Such unauthorized modification and potential data exfiltration could negatively impact compliance with data protection standards and regulations like GDPR and HIPAA, which require safeguarding personal and sensitive data against unauthorized access and alteration.

Detection Guidance

This vulnerability involves unauthorized modification of form action metadata via the `wpr_update_form_action_meta` AJAX action accessible without authentication. Detection can focus on monitoring HTTP requests to the AJAX endpoint that include this action.

  • Check web server logs for POST requests to admin-ajax.php with the parameter `action=wpr_update_form_action_meta` coming from unauthenticated sources.
  • Use command-line tools like curl or wget to test if the AJAX action is accessible without authentication.
  • Example curl command to test accessibility: `curl -X POST -d "action=wpr_update_form_action_meta" https://yourwordpresssite.com/wp-admin/admin-ajax.php`
  • Look for suspicious changes in post meta related to form actions such as email, submissions, Mailchimp, and webhook settings.
Mitigation Strategies

Immediate mitigation steps include restricting access to the vulnerable AJAX action and updating the plugin.

  • Update the Royal Addons for Elementor plugin to a version later than 1.7.1056 where this vulnerability is fixed.
  • If an update is not immediately possible, block or restrict access to the `wpr_update_form_action_meta` AJAX action via web application firewall rules or server configuration.
  • Monitor and audit changes to form action metadata to detect unauthorized modifications.
Impact Analysis

This vulnerability can allow unauthenticated attackers to modify form action configuration metadata on any post using the Royal Addons plugin.

  • Attackers can tamper with email and webhook actions, potentially redirecting or intercepting data.
  • Data exfiltration may occur through modified webhook URLs.
  • Such unauthorized modifications can disrupt normal form processing and compromise data integrity.
