CVE-2025-12355
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedThe Payaza plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the 'wp_ajax_nopriv_update_order_status' AJAX endpoint in all versions up to, and including, 0.3.8. This makes it possible for unauthenticated attackers to update order statuses.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceThe Payaza WordPress plugin has a broken access control vulnerability in the wp_ajax_nopriv_update_order_status AJAX action. This endpoint, accessible to unauthenticated users due to the 'nopriv' registration, lacks a capability check (e.g., current_user_can()) before allowing order status modifications, enabling any visitor to alter order data.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Verify Payaza plugin installation and activation statusIn WordPress admin, navigate to Plugins > Installed Plugins and locate Payaza in the list. Confirm it shows as 'Active'.Affected if The Payaza plugin is installed and active in WordPress.
-
Identify installed Payaza plugin versionIn the Plugins list, click on the plugin name to view details, or check the plugin file header in wp-content/plugins/payaza/*.php for the Version: field.Affected if The installed version is lower than 0.3.9 or cannot be determined.
-
Confirm vulnerable AJAX action is registeredSearch plugin PHP files for 'wp_ajax_nopriv_update_order_status' or 'add_action("wp_ajax_nopriv_update_order_status"' to verify the action is hooked.Affected if The 'wp_ajax_nopriv_update_order_status' action is registered and accessible to unauthenticated users.
-
Check for missing capability verification in AJAX handlerLocate the callback function for update_order_status and verify if it contains a call to current_user_can() or similar capability check before processing the order status change.Affected if No capability check (e.g., current_user_can) is present before processing the order status modification.
A user is affected if the Payaza plugin is active with a version prior to 0.3.9 and the update_order_status AJAX endpoint is accessible to unauthenticated users without capability verification.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataAdd a WordPress capability check (such as current_user_can('manage_options') or appropriate e-commerce capability) and nonce verification to the AJAX handler before processing any order status changes. Update to version 0.3.9 or later if available.
