Although ERC20Boost.decrementGaugesBoostIndexed function would require user to remove all of her or his boost from a deprecated gauge at once, such user can instead call ERC20Boost.decrementGaugeBoost function for multiple times to utilize such deprecated gauge and decrement its userGaugeBoost for multiple times

Lines of code Vulnerability details Impact When the gauge input corresponds to a deprecated gauge, calling the following ERC20Boost.decrementGaugeBoost function can still execute gaugeState.userGaugeBoost -= boost.toUint128 if boost = gaugeState.userGaugeBoost is false. function...
