CVE-2026-34383 Admidio: CSRF and Form Validation Bypass in Inventory Item Save via `imported` Parameter

What is CVE-2026-34383?

CVE-2026-34383 is a medium-severity vulnerability in admidio, published on 31 Mar 2026. Any signed-in user can exploit it over the network, with no action from the victim.

Official description

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.

Weakness: CWE-352, CWE-20
