Vulnerability Title
GLPI: Unexpected access to update operations through the API
Source: CVE Program / CVE List V5
Vulnerability Description
GLPI is a free asset and IT management software package. From 11.0.0 until 11.0.8, a low-privileged authenticated user can use the new API (v2) to perform update operations that the same user is normally forbidden to perform through the user interface. The API update flow does not consistently enforce the applicable authorization checks. This issue is fixed in version 11.0.8.
