Users can use flashloans to get higher share of accrued token
Lines of code Vulnerability details Impact Detailed description of the impact of this finding. Users' vtoken balance is one of the factors to determine their score. Malicious users can just use some flashloan services that offer these vtokens to boost their balance temporarily, hence boosting the...
CVE-2023-42460
Vyper is a Pythonic Smart Contract Language for the EVM. The abidecode function does not validate input when it is nested in an expression. 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...
Out-of-bounds
Vyper is a Pythonic Smart Contract Language for the EVM. The abidecode function does not validate input when it is nested in an expression. 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...
Intrinsic arbitrage from price discrepancy
Lines of code Vulnerability details Impact The up to 2 % price discrepancy from Chainlink creates an intrinsic arbitrage. Especially, it makes withdrawals worth more than deposits in the sense that one can immediately withdraw more than just deposited. Proof of Concept When depositing ETH into...
Vyper Security Vulnerability
Vyper is the Pythonic smart contract language for EVM. Vyper suffers from a security vulnerability that stems from allowing an attacker to bypass boundary checks via constructabidecode...
Swap functionality to sell rewards is too permissive and could cause accidental or intentional loss of value
Lines of code Vulnerability details Summary While the intention is to use the 0x protocol to sell rewards, the implementation doesn't provide any basic guarantee this will correctly happen and grants the rewarder arbitrary control over the tokens held by the strategy. Impact Rewards earned in the...
Forced relock in VotiumStrategy withdrawal causes denial of service if Convex locking contract is shutdown
Lines of code Vulnerability details Summary The VotiumStrategy withdrawal process involves relocking CVX tokens, which can potentially lead to a denial of service and loss of user funds if the underlying vlCVX contract is shutdown. Impact When withdrawals are executed in VotiumStrategy, the...
Missing slippage control when directly interacting with the VotiumStrategy contract
Lines of code Vulnerability details Summary Direct deposits and withdrawals within VotiumStrategy lack any slippage controls, which opens up the possibility of sandwich attacks and Miner Extractable Value MEV exploits. Impact Interactions in the AfEth protocol often require the exchange of ETH fo...

No exploitation details are provided in the documents, and the vulnerabili...
CVE-2023-42443
Vyper is a Pythonic Smart Contract Language for the Ethereum Virtual Machine EVM. In version 0.3.9 and prior, under certain conditions, the memory used by the builtins rawcall, createfromblueprint and createcopyof can be corrupted. For rawcall, the argument buffer of the call can be corrupted,...
CVE-2023-42441
Vyper is a Pythonic Smart Contract Language for the Ethereum Virtual Machine EVM. Starting in version 0.2.9 and prior to version 0.3.10, locks of the type @nonreentrant"" or @nonreentrant'' do not produce reentrancy checks at runtime. This issue is fixed in version 0.3.10. As a workaround, ensure...
