claimRewardAsMochi in the ReferralFeePoolV0 ignores slippage. This is not a desirable design. There are a lot of MEV searchers in the current network. Swapping assets with no slippage control would get rekted. Please refer to https://github.com/flashbots/pm.
Given the current state of the Ethereum network, users would likely be sandwiched. I consider this is a high-risk issue.

I recommend adding minReceivedAmount as a parameter.
Also, the front-end should calculate the min amount with the current price.
