Similar to many lending protocols, the Revert Lend protocol has a feature allowing one user to liquidate another. The purpose of this liquidation mechanism is to settle outstanding loans and maintain protocol stability. However, a user eligible for liquidation can exploit this process by executing a DoS attack. This involves front-running the liquidate() intended for their liquidation, by calling the borrow() with a minimal amount and changing their debtShares, which reverts the liquidation.
