[1] Array out-of-bounds

Array out-of-bounds access causes a revert without any informative error message (it raises a Panic(0x32) exception).

Recommendation

Check that an index which is used to access an array element fits the array's boundaries before accessing that array element.

Code References

AxelarAuthWeighted.sol: line 105 (operatorIndex must be < weights.length)

The code will revert as intended, I will mark this as Refactoring
