CVE-2025-3278
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 UrbanGo Membership plugin for WordPress is vulnerable to privilege escalation in versions up to, and including, 1.0.4. This is due to the plugin allowing users who are registering new accounts to set their own role or by supplying 'user_register_role' field. This makes it possible for unauthenticated attackers to gain elevated privileges by creating an account with the administrator role.
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 UrbanGo Membership WordPress plugin versions up to 1.0.4 contains a privilege escalation vulnerability where the user registration function does not properly validate or restrict the role assigned to new users. Attackers can supply a 'user_register_role' parameter during registration to automatically grant themselves administrator-level privileges, gaining full site control.

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.
-
Identify if UrbanGo Membership plugin is installedNavigate to WordPress admin > Plugins > Installed Plugins and look for 'UrbanGo Membership' in the list, or check the /wp-content/plugins/ directory for an 'urbango-membership' folderAffected if The UrbanGo Membership plugin is present in the plugins directory regardless of activation status
-
Determine the installed plugin versionIn WordPress admin > Plugins, find UrbanGo Membership and view the version number under the plugin name, or read the main plugin file (usually urbango-membership.php) and look for the 'Version' header in the plugin comment blockAffected if The version number is 1.0.4 or lower
-
Verify WordPress user registration is enabledGo to WordPress admin > Settings > General and check 'Membership: Anyone can register' is checked, or check the 'users' capability in WordPress options tableAffected if User registration is enabled on the WordPress site (anyone can register setting is ON)
-
Inspect registration form for vulnerable parameterView the source of the user registration page on the frontend and search for a form field named 'user_register_role' or 'role', or inspect HTTP POST requests when submitting a registration to see if the 'user_register_role' parameter is being sentAffected if The registration form accepts or processes a 'user_register_role' parameter that can be controlled by the user
A user is affected if UrbanGo Membership plugin versions 1.0.4 or below is installed, WordPress user registration is enabled, and the plugin accepts a user_register_role parameter that can be manipulated to assign administrator roles during registration
