AfEth deposits could use price data from an invalid Chainlink response

Lines of code Vulnerability details Summary The current price implementation for the VotiumStrategy token uses a potentially invalid Chainlink response. This price is then used to calculate the price of AfEth and, subsequently, the amount of tokens to mint while depositing. Impact The price of...

AfEth price calculation doesn't factor locked tokens held in contract balance

Lines of code Vulnerability details Summary When withdrawals are enqueued in AfEth, the implementation will remove the tokens from the caller and lock these in the contract until the withdrawal is made effective. These tokens still count in the supply, and must not be considered during price...

cvxPerVotium() calculation will return zero if all CVX tokens are pending withdrawal as obligations

Lines of code Vulnerability details Summary The implementation of cvxPerVotium contains an edge case that causes it to return an invalid zero value price. Impact The cvxPerVotium function present in the VotingStrategy contract is used to measure the number of held CVX tokens per vAfEth. 144:...

Incorrect AfEth.price() calculation

Lines of code Vulnerability details Impact AfEth.price may be calculated as too low. Proof of Concept AfEth.requestWithdraw does not burn the afEth but only transfers it to itself. Hence the withdrawRatio is calculated using only the free supply of afEth: AfEth.solL180-L185 // ratio of afEth bein...

Lines of code Vulnerability details Impact The previously identified vulnerability of potential rounding issues during reward calculations has not been fully mitigated. The current strategy to keep remainders and use them in subsequent claimAndSyncRewards calls does not adequately address the iss...

price() in AfEth.sol doesn't take afEth held for pending withdrawals into account

Lines of code Vulnerability details Bug Description In AfEth.sol, the price function returns the current price of afEth: AfEth.solL133-L141 function price public view returns uint256 if totalSupply == 0 return 1e18; AbstractStrategy vEthStrategy = AbstractStrategyvEthAddress; uint256...

Users can deposit() even when Chainlink's price feed for CVX is stale

Lines of code Vulnerability details Bug Description In VotiumStrategy.sol, the price of vAfEth is determined by the price function: VotiumStrategy.solL31-L33 function price external view override returns uint256 return cvxPerVotium ethPerCvxfalse / 1e18; As seen from above, it calls ethPerCVX wit...

Uses of abidecode can be constructed which allow for bounds checking to be bypassed resulting in incorrect results. This issue has not yet been fixed, but a...

VotiumStrategyCore.applyRewards can be sandwhiched to make profit

Lines of code Vulnerability details Impact VotiumStrategyCore.applyRewards can be sandwhiched to make profit. Proof of Concept VotiumStrategyCore.applyRewards function will swap all rewards of contract into eth and then stake them into safEth or vEth contract. As result price of afEth token will...

Stale cvx price can be used while depositing

Lines of code Vulnerability details Impact Stale cvx price can be used while depositing Proof of Concept When user deposits, then price of afEth token is calculated. It's needed to know how many tokens user will receieve. This price consists of safEth price and vEth price. This is how price is...
