CVE-2026-121559 Details
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.
A privilege escalation vulnerability has been identified in GLPI versions 10.0.0 prior to 10.0.28 and 11.0.0 prior to 11.0.10. This vulnerability allows authenticated users to gain elevated profiles by cloning accounts. Specifically, a user with the Technician profile can clone a Super-Admin account by assigning a new login and password. The issue arises because the cloning process copies all Profile_User and Group_User assignments without proper permission checks, enabling the creation of a Super-Admin account under the attacker's control.
Users can upgrade to GLPI version 10.0.28 or 11.0.10 to address this vulnerability.
