Is this vulnerability remotely exploitable over the internet?

It can be, if the GLPI instance is exposed and an attacker can obtain credentials with permissions to create or manage dropdowns. The exploit path is through normal web requests to the GLPI interface.

What level of access does an attacker need to exploit this issue?

The attacker must be an authenticated GLPI user with sufficient rights to create or modify dropdowns via the Fields plugin. They do not need direct filesystem or database access.

What is the safest general fix pattern for this type of vulnerability?

Ensure that configuration and dropdown data is always treated as passive text, strictly validate allowed formats, and prevent any user-controlled values from influencing PHP code paths. Avoid designs where configuration is interpreted as executable code.
