CVE-2026-121559

High

Description

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.
