Submit #742677: Wekan <8.21 Improper access control on migration endpoints (CWE-284)info

TitleWekan <8.21 Improper access control on migration endpoints (CWE-284)
DescriptionAttachment-migration methods did not consistently enforce that the caller had sufficient privileges for the target board. The fix adds checks requiring the user be a board admin or instance admin for migration execution, and requires board visibility for progress/status style calls.
