Integer Overflow

Lines of code Vulnerability details Impact The owner of the ActivePool contract can set yield distribution parameters that do not add to the expected 10000 BPS. This would cause the rebalance function to send the incorrect number of tokens when using the splits. Proof of Concept Calling...

Last good price might be not good if both Tellor and Chainlink prices are unreliable

Lines of code Vulnerability details Impact Calling from Pricefeed.sol, fetchPrice returns the last good price seen by the protocol whenever both Chainlink and Tellor fail to be reliable. The protocol features multi-collateral support which eventually accepts assets that are volatile in nature, du...

setWithdrawalQueue never removes items from the queue and can get out of gas

Lines of code Vulnerability details Impact setWithdrawalQueue calls delete, this sets to 0 each element of the array rather than removing elements what it's done with .pop. After that, strategies are pushed in a for loop, therefore, each time setWithdrawalQueue is called, length of the queue is...

Attacker contract can avoid being blocked

Lines of code Vulnerability details Impact A Malicious attacker can interact with the system and selfdestruct his own contract then use CREATE2 to recreate it at same address when he needs to interact with the system again. Proof of Concept Tools Used Manual Review Recommended Mitigation Steps...

Re-entrancy inside BorrowOperations if collateral is ERC777

Lines of code Vulnerability details Impact Invariant violations through re-entrancy if the collateral token is ERC777 Proof of Concept If the collateral token will be an ERC777 token, a malicious user could use the safeTransfer from L231 to re-enter the BorrowOperations contract context and call...
