What is CVE-2026-121559?

GLPI versions 10.0.0 before 10.0.28 and 11.0.0 before 11.0.10 have a vulnerability that allows authenticated users with a Technician profile to escalate privileges. By exploiting the User::getCloneRelations() function, which does not implement adequate permission checks, an attacker can clone a Super-Admin account, gaining unauthorized access through a new login and password. This flaw presents significant security risks as it can lead to unauthorized control over sensitive administrative functions.

Affected Version(s)

GLPI 10.0.0 < 10.0.28

GLPI 11.0.0 < 11.0.10
