While flash loans have several legitimate use cases, they can also be used to fund various types of attacks on DeFi protocols. Once a vulnerability is uncovered, a malicious actor can manipulate certain functions of the protocol using capital acquired via a flash loan and make a profit while potentially draining funds from its smart contracts. The key issue is not the flash loans themselves, but rather the existing vulnerabilities in the DeFi protocols that may be exploited through flash loan-funded attacks, particularly those that rely on a single centralized price oracle as the sole source of market data.
