Potential front-running attacks

Summary

Due to the absence of proper protection mechanisms, front-running attacks could be possible, where an attacker could exploit the loan creation or liquidation process for their own benefit.

Vulnerability Detail

The loan creation and liquidation processes do not have adequate protection mechanisms in place to prevent front-running attacks. As a result, an attacker could potentially monitor pending transactions and insert their own transactions with higher gas prices, allowing them to manipulate the process for their benefit.

Impact

Front-running attacks could compromise the fairness and integrity of the loan creation and liquidation processes, potentially resulting in financial loss for users or the platform.

Tool used

Manual Review

Recommendation

Implement protection mechanisms, such as commit-reveal schemes or batched transactions, to prevent front-running attacks during the loan creation and liquidation processes. This will help ensure the fairness and integrity of these processes and protect users and the platform from financial loss.
