CVE-2026-121559 · Severity: high · CVSS 7.2 · Published 2026-11-03

GLPI is an open-source IT asset management system used by organizations to track hardware, software, and support tickets. A flaw in the account cloning feature allows authenticated users with a Technician profile to create a copy of a Super-Admin account under their own control, granting them complete administrative access to the system. An attacker could use this to compromise the entire IT environment managed by GLPI.

## How to fix

## Technical details

The User::getCloneRelations() method copies all Profile_User and Group_User assignments without performing permission validation during account cloning. An authenticated Technician can exploit this to clone a Super-Admin account, obtaining a new account with identical administrative privileges but under attacker control. This represents a privilege escalation from Technician to Super-Admin via insufficient authorization checks in the cloning logic.

## Affected products
