Description
AppFlowy-Cloud 0.9.64 fails to verify that requested collab objects belong to the workspace in authorization checks, allowing attackers to access documents and database rows across workspaces. Attackers can supply a victim's object ID with their own workspace ID to bypass access controls and read, modify, or delete cross-workspace data.
