Overview
Affected versions of this package are vulnerable to Race Condition through the State object computation process. An attacker can cause a chain split by exploiting inconsistencies in the ProposerPriority field during state synchronization.
Note: This is only exploitable if validators run state sync using RPC nodes that are malicious or report invalid states for the proposer selection algorithm.
