Submit #742678: Wekan <8.21 Improper access control (CWE-284)info

TitleWekan <8.21 Improper access control (CWE-284)
DescriptionMethods involved in moving or validating attachment storage did not consistently enforce board visibility or required privileges for the referenced board/attachments, which could enable unauthorized operations on attachment storage workflows. The fix adds authorization/visibility checks before proceeding and tightens validation.
