CVE-2025-67579
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 · uneditedMissing Authorization vulnerability in vanquish User Extra Fields wp-user-extra-fields allows Exploiting Incorrectly Configured Access Control Security Levels.This issue affects User Extra Fields: from n/a through <= 16.8.
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 · moderate confidenceMissing Authorization vulnerability in the WordPress plugin 'wp-user-extra-fields' (versions <= 16.8) allows unauthenticated or lower-privileged users to access functionality intended for higher-privilege users due to incorrectly configured access control security levels. The plugin fails to properly validate user permissions before allowing access to sensitive user extra field operations.

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.
-
Confirm plugin installation and versionNavigate to WordPress Admin > Plugins and locate 'wp-user-extra-fields' in the installed plugins list. Note the version number displayed. Alternatively, inspect the plugin's main PHP file (wp-user-extra-fields.php) and search for a version definition (e.g., 'Version: X.X.X').Affected if The installed version is 16.8 or lower.
-
Identify plugin AJAX endpointsInspect the plugin's main PHP file and search for 'add_action' calls registering AJAX actions (look for 'wp_ajax_' and 'wp_ajax_nopriv_' hooks). Record the action names associated with user extra field operations.Affected if AJAX endpoints exist that are registered with 'wp_ajax_nopriv_' (allowing unauthenticated access) or lack capability checks within their handler functions.
-
Review AJAX handler authorization logicIn the plugin PHP files, locate the callback functions for the identified AJAX actions. Examine each handler for WordPress capability checks (e.g., 'current_user_can()', 'check_ajax_referer()', or role verification like 'administrator' role).Affected if The AJAX handlers perform no capability checks, or the checks allow access to subscribers, editors, or other non-administrator roles.
-
Test unauthenticated access to sensitive featuresUsing a browser or HTTP tool (like curl), attempt to access the plugin's AJAX endpoints directly without authenticating or with a low-privilege account (subscriber role). Send a request to wp-admin/admin-ajax.php with the identified action parameters.Affected if The requests execute successfully and return sensitive data or perform actions (like creating/modifying user extra fields) without returning a permission denied error.
If the plugin version is 16.8 or lower AND its AJAX endpoints or sensitive functions can be accessed without proper WordPress capability verification, the environment is affected by this authorization bypass.

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 dataImplement proper authorization checks (using WordPress capability checks like 'manage_options' or role verification) on all sensitive plugin functions and AJAX endpoints. Restrict access to user extra field management features to administrators only.
