Overview:
Enable CQL to return restricted content when a valid admin key is provided, in the same way it works for other API endpoints like space lookups.

Current Behavior:

• Admins can retrieve restricted spaces using the GET /wiki/api/v2/spaces endpoint.

• However, CQL queries do not return restricted content, even when the same admin key and header are used.

Expected Behavior:
CQL should return content from restricted spaces if the request includes a valid admin key and the appropriate header (Atl-Confluence-With-Admin-Key: true), ensuring consistency with other admin-enabled endpoints.

Use Case:
This enhancement would allow admin users or automated systems to run comprehensive content searches across all spaces, including restricted ones, improving administrative workflows, audits, and content management.

Impact:

• Improves consistency across the API.

• Enables full visibility for admin users performing content queries.

• Reduces confusion and avoids the need for less efficient workarounds.
