Description
The MStore API plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 4.18.3. This is due to the update_user_profile() function in controllers/flutter-user.php processing the 'meta_data' JSON parameter without any allowlist, blocklist, or validation of meta keys. The function reads raw JSON from php://input (line 1012), decodes it (line 1013), authenticates the user via cookie validation (line 1015), and then directly iterates over the user-supplied meta_data array passing arbitrary keys and values to update_user_meta() (line 1080) with no sanitization or restrictions. This makes it possible for authenticated attackers, with Subscriber-level access and above, to modify arbitrary user meta fields on their own accounts, including sensitive fields like wp_user_level (to escalate to administrator-level legacy checks), plugin-specific authorization flags (e.g., _wpuf_user_active, aiowps_account_status), and billing/profile fields with unsanitized values (potentially enabling Stored XSS in admin contexts). Note that wp_capabilities cannot be directly exploited this way because it requires a serialized array value, but wp_user_level (a simple integer) and numerous plugin-specific meta keys are exploitable.

Title: plugin The MStore API para WordPress, Description: El plugin MStore API para WordPress es vulnerable a Referencia Directa a Objeto Insegura en todas las versiones hasta la 4.18.3, inclusive. Esto se debe a que la función update_user_profile() en controllers/flutter-user.php procesa el parámetro JSON 'meta_data' sin ninguna lista blanca, lista negra o validación de claves meta. La función lee JSON sin procesar de php://input (línea 1012), lo decodifica (línea 1013), autentica al usuario mediante validación de cookie (línea 1015), y luego itera directamente sobre el array meta_data proporcionado por el usuario pasando claves y valores arbitrarios a update_user_meta() (línea 1080) sin saneamiento ni restricciones. Esto hace posible que atacantes autenticados, con acceso de nivel Suscriptor y superior, modifiquen campos meta de usuario arbitrarios en sus propias cuentas, incluyendo campos sensibles como wp_user_level (para escalar a comprobaciones heredadas de nivel de administrador), indicadores de autorización específicos del plugin (por ejemplo, _wpuf_user_active, aiowps_account_status), y campos de facturación/perfil con valores no saneados (lo que podría habilitar XSS Almacenado en contextos de administrador). Tenga en cuenta que wp_capabilities no puede ser explotado directamente de esta manera porque requiere un valor de array serializado, pero wp_user_level (un entero simple) y numerosas claves meta específicas del plugin son explotables.
