CVE-2023-32058

CVE-2023-32058 affects the Vyper language (EVM smart contracts). Prior to version 0.3.8, there was a missing overflow check for loop variables when iterating with patterns like for i in range(a, a + N). This could cause the loop variable’s type to overflow. The issue appears specifically in for i...

Lack of Access Control in GrantFund Smart Contract's fundTreasury Function

Lines of code Vulnerability details Impact The fundTreasury function in the GrantFund.sol contract allows anyone to add funds to the contract's treasury without any access control, which can lead to unauthorized access to the contract's funds. The problem with this function is that it doesn't hav...

Incorrect Calculation of Max Amount of Quote Tokens in moveLiquidity() Function in PositionManager.sol.

Lines of code Vulnerability details Impact The updateInterest function is called before retrieving the fromPosition value from positionsparams.tokenIdparams.fromIndex in the moveLiquidity function. This means that the bucketDeposit value may not reflect the current accrued interest, which can...

Division by Zero Vulnerability in _calculateNewRewards function.

Lines of code Vulnerability details Impact The calculateNewRewards function in the smart contract performs a division operation with totalInterestEarnedInPeriod, which could be zero, but there is a problem that can result in a division-by-zero error, causing the smart contract to behave...

Risk of Gas Limit Exceedance During Proposal Sorting
