## What is CVE-2026-41658?

CVE-2026-41658 is a medium-severity missing authorization vulnerability in admidio, published on 7 May 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 5.0.9, the Admidio inventory module enforces authorization for destructive operations (delete, retire, reinstate) only in the UI layer by conditionally rendering buttons. The backend POST handlers at modules/inventory.php for item_delete, item_retire, item_reinstate, item_picture_upload, item_picture_save, and item_picture_delete perform CSRF validation but never check whether the requesting user is an inventory administrator. Any authenticated user who can access the inventory module can permanently delete any inventory item and all its associated data. This issue has been patched in version 5.0.9.

Weakness: CWE-862 (Missing Authorization)
