## Overview

GLPI 10.0.0 before 10.0.28 and 11.0.0 before 11.0.10 contains a privilege escalation vulnerability that allows authenticated users to obtain elevated profiles by cloning accounts. A user with the Technician profile can clone a Super-Admin account with a new login and password, since User::getCloneRelations() copies every Profile_User and Group_User assignment without permission checks, yielding an attacker-controlled Super-Admin account.

## Affected

- `GLPI >= 10.0.0 < 10.0.28`
- `GLPI >= 11.0.0 < 11.0.10`

## Remediation

Refer to the linked advisories for vendor-supplied fixes and affected version ranges.
