Issue search API protection
Available since v. 5.31.*
The issue search API will return information about all available fields in Jira if there is no defined query parameter “fields”.
However, in the case of large instances with a significant number of additional custom fields, such queries may potentially impact the overall performance of the application.
With this option, you can determine whether the API should be additionally secured for such scenarios.
If enabled, the API will refrain from returning search results for queries that lack a “fields” query parameter.
