CVE-2026-4024 — Royal Addons for Elementor security vulnerability
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.

Matched remediation archetype
Authorization bypass, IDOR, and cross-tenant access
This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.
Check exposure
- Map object and action authorization checks across API, UI, batch, import/export, and background-job paths.
- Identify tenant, ownership, role, and policy boundaries for affected resources and administrative operations.
- Use synthetic fixtures to compare intended access matrices without accessing another user's real data.
Remediate safely
- Enforce server-side authorization at each resource access and state transition using the authenticated principal and trusted tenant context.
- Scope data queries by tenant and ownership; treat client-supplied identifiers, roles, and policy claims as untrusted.
- Add deny-by-default policy tests for horizontal and vertical access across every affected transport.
