Summary

Babylon vulnerable to chain halt when a message modifies the validator set at the epoch boundary

Details

Summary

Sending a message that modifies the validator set at the epoch boundary halts the chain.

Impact

Denial of Service - Comos-sdk prevents modifying the validator set from two different modules - https://github.com/cosmos/cosmos-sdk/blob/release/v0.50.x/types/module/module.go#L811. Such an operation leads to panic and chain halt.
