Summary

Execution failure of mowMultiple can cause exceeding of block gas limit

Vulnerability Details

In the mowMultiple function, there is a loop that iterates through the tokens array. The loop condition is i < tokens.length, which thereby causes gas consumption with each iteration. If the token array is large enough, the block gas limit can be exceeded

Impact

This can result to wastage of gas fees for users. Attackers can also provide a large array of tokens enough to cause DOS

Recommendations

Limit the number of iterations in loops, especially when dealing with arrays. And also, large transaction can be broken into multiple transactions
