Maker community scrambles to fix long-standing vulnerability to flash loans

The MakerDAO (MKR) community is urgently implementing measures to prevent voting manipulation through flash loans. This was precipitated by what is likely the first instance of the feature being used to influence a DeFi governance vote on Oct. 26.

According to a post published by community member LongForWisdom, someone used a flash loan to force a governance proposal through. BProtocol, a service that lets users pool liquidity to join in Maker debt auctions, came forward as the culprit.
