Vulnerability Details

As per the code comments in the links above, the structs: Deposit, GerminatingStalk and MowStatus were supposed to have a buffer parameter which would allow any additions in the future but in the current code, the _buffer parameter is missing

Impact

Since there is no _buffer storage reserve, adding additional fields in these structs won't be possible in the future

Tools Used

Manual Review

Recommendations

Add a _buffer field to these structs
