Summary

The mintFertilizer() function is used to purchase Fertilizer from the Barn Raise with the Barn Raise token. According to Protocol, when beginBarnRaiseMigration() is invoked to begin the process of migration of the Barn Raise to a new Well, the following is required:

However, the mintFertilizer() does not implement a check for the status of Barn Raise migration.

Vulnerability Details

Impact

This omission allows for purchase of Fertilizer during migration which is against protocol.
