How widely exploitable is this vulnerability?

Exploitability depends on who can perform CSV imports. In many deployments, this capability is limited to administrators or staff roles; if those accounts are compromised or misused, stored XSS payloads can be planted and later executed in other users' browsers.

Does an attacker need direct access to the Chamilo interface to exploit this?

Typically, yes, they need sufficient privileges to upload or submit a CSV file that Chamilo processes. However, in some workflows CSVs may be prepared by others and handed off to an administrator, which can be abused via social engineering.

What is the safest general fix pattern for this class of bug?

The most robust fix is to enforce centralized, context-aware output encoding for all user-controlled fields, combined with strict normalization and validation of CSV-imported fields so that they only contain characters appropriate for names and usernames.
