Piedao: UwU Lend hack incident caused by price oracle manipulation

according to analysis by Shield, the fundamental reason for the $19.4 million loss of UwU Lend today due to a hacker attack is a price oracle issue.

Specifically, the pricing of the sUSDe asset comes from the median of multiple sources. Among them, five, namely FRAXUSDe, USDeUSDC, USDeDAI, USDecrvUSD, and GHOUSDe, were manipulated during the hacker attack.
