Teku and Besu patch Ethereum flaw that could redirect ETH staking rewards

Ethereum client developers Teku and Besu released security updates fixing a certificate vulnerability that could let attackers impersonate services validators rely on and potentially redirect block rewards. The flaw affects validator infrastructure rather than the core protocol, and patches are now available. Traders should care because a credible attack path against validator rewards could undermine staking confidence, but the coordinated fix limits the risk.
