CVE-2026-34383

Estado: AnalizadaBaja (3.5)—

Admidio is an open-source user management solution. Prior to version 5.0.8, the inventory module's item_save endpoint accepts a user-controllable POST parameter imported that, when set to true, completely bypasses both CSRF token validation and server-side form validation. An authenticated user can craft a direct POST request to save arbitrary inventory item data without CSRF protection and without the field value checks that the FormPresenter validation normally enforces. This issue has been patched in version 5.0.8.

Un usuario autenticado puede elaborar una solicitud POST directa para guardar datos arbitrarios de elementos del inventario sin protección CSRF y sin las comprobaciones de valor de campo que la validación de FormPresenter normalmente aplica. Este problema ha sido parcheado en la versión 5.0.8."
