Is this vulnerability remotely exploitable over the network?

Yes, but within the constraint that the attacker must interact with the GLPI web interface as an authenticated administrator (or an account with comparable template-editing rights). There is no need for direct shell access; exploitation occurs through HTTP requests to administrative endpoints.

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

Exploitation generally requires administrative-level access to GLPI or any role permitted to create or modify templates that are later rendered by the server. Compromise of such an account—through phishing, password reuse, or other means—can be enough to trigger the vulnerability.

What is the safest general fix pattern for developers and maintainers?

The most robust fix is to ensure that templates are never treated as arbitrary executable code. This includes adopting a restricted template engine configuration, disallowing dangerous functions and dynamic evaluation, and validating or escaping template content so that only harmless presentation logic is processed.
