read-only reentrancy

Read-only reentrancy exploits the fact that another contract's view function can return stale state mid-execution.只读重入利用了另一个合约的 view 函数可以在执行中途返回过时状态的事实。

The read-only reentrancy vector caught several protocols off-guard because they assumed view functions were always safe to call.只读重入向量让几个协议措手不及，因为它们假设 view 函数调用总是安全的。
