Flash loans can significantly increase a single voters weight and be used to impact the voting outcome. A voter can borrow a significant quantity of tokens to increase their voting weight in a transaction within which, they also deterministically  influence the voting outcome to their choice.
This has already happened in the case of MakerDAO governance where a flash loan was used to affect voting outcome and noted by the Maker team as: a practical example for the community that flash loans can and may impact system governance
Given that flash loans are a noted concern, the impact of it to DAO governance which can control all critical protocol parameters should be mitigated as in other places.
Recommend accounting for flash loans in countMemberVotes() by using weight from previous blocks or consider capping the weight of individual voters. (L158-L163)
