Summary
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.
Risk Assessment
An attacker can gain full administrative privileges in GLPI, leading to system compromise and access to sensitive data. This may result in further escalation within the environment.
Recommendation
Update GLPI to version 10.0.28 or 11.0.10 (or later). Until updated, restrict account cloning capabilities and monitor for new administrative account creation.
