The `RAACMinter::setMaxEmissionRate` fails to check against `MAX_BENCHMARK_RATE` leading to excessive token minting

kiteweb3

Summary

The RAACMinter::setMaxEmissionRatefunction lacks validation against theMAX_BENCHMARK_RATE` constant. This allows to set an emission rate higher than the intended protocol maximum. This can lead to excessive token minting beyond protocol design limits causing an economic imbalance in the system.

Vulnerability Details

function setMaxEmissionRate(uint256 _maxEmissionRate) external onlyRole(UPDATER_ROLE) {
@> if (_maxEmissionRate <= minEmissionRate) revert InvalidMaxEmissionRate();
uint256 oldRate = maxEmissionRate;
maxEmissionRate = _maxEmissionRate;
emit MaxEmissionRateUpdated(oldRate, _maxEmissionRate);
}

Impact

The RAACMinter::setMaxEmissionRate only checks that the new rate is greater than minEmissionRate but fails to validate against MAX_BENCHMARK_RATE, allowing setting of arbitrarily high emission rates. This can lead to excessive token minting beyond protocol design limits causing an economic imbalance in the system.

Recommendations

Add validation against MAX_BENCHMARK_RATE in the setMaxEmissionRate function.

function setMaxEmissionRate(uint256 _maxEmissionRate) external onlyRole(UPDATER_ROLE) {
if (_maxEmissionRate <= minEmissionRate) revert InvalidMaxEmissionRate();
+ if (_maxEmissionRate > MAX_BENCHMARK_RATE) revert MaxEmissionRateExceedsLimit();
uint256 oldRate = maxEmissionRate;
maxEmissionRate = _maxEmissionRate;
emit MaxEmissionRateUpdated(oldRate, _maxEmissionRate);
}
