CVE-2023-41052

Vyper CVE-2023-41052 affects the Pythonic smart contract language Vyper. In affected versions, the evaluation order of arguments to builtins uint256_addmod, uint256_mulmod, ecadd, and ecmul does not follow source order, which can cause side effects in one argument to be relied upon by others. The...

Vulnerability in swapGivenInputAmount Function that could Leads to Unintended Token Draining

Lines of code Vulnerability details Impact The vulnerability discovered in the swapGivenInputAmount function has the potential to cause unintended token draining in the smart contract. Due to an incorrect check for a negative result in the code requireresult 0;, the function may allow swaps to...

Swaps affect LP token mint/burn during liquidity addition/removal

Lines of code Vulnerability details Impact The LP token removal/addition forces a recalculation of the bonding curve, and the utility of the curve. The utility curve in proteus looks like the graph below, where the point A represents a certain composition of the pool. If we try to remove add/remo...
