## Technical details

The `copyBoard` Meteor DDP method in `server/publications/boards.js` failed to implement authorization checks, such as verifying `this.userId` or board membership. An authenticated attacker could invoke this method with a target `boardId` to create a full clone of a private board, including its cards, checklists, and custom fields. Furthermore, the method allowed property injection by looping over caller-supplied properties, enabling attackers to modify the new board's permissions (e.g., making it 'public') or adding themselves as an administrator. While the REST API correctly enforced admin checks, the DDP implementation remained vulnerable until version 9.32, which now requires board admin privileges (`board.hasAdmin`).
