In the current implementation of Jira Software and Jira Service Management, access to the /rest/api/2/customFields endpoint is restricted to users with Administrator privileges. This endpoint provides significant capabilities for adjusting and managing custom fields.

We propose introducing access to a modified version of this endpoint for non-administrative users and be read-only. This would facilitate information gathering and enable system checks without requiring Administrator-level permissions. Such a feature would enhance user efficiency and maintain security by limiting necessary administrative access.
