Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Auth Bypass: The lack of domain and message sender binding in signatures allowed attackers to perform replay and forgery attacks, potentially hijacking referral rewards and trade processing fees. The fix strictly binds signatures to both msg.sender and the unique contract instance address.
Auth Bypass: Public visibility of administrative token allowance methods (such as approveInternal) allowed arbitrary external accounts to manipulate allowances and bypass standard transfer authorization barriers.
Access Control: Missing operator approval validations within standard ERC1155 token transfers permitted unauthorized transfers of users' shares.
