Sigma Prime Releases High-Priority Lighthouse Security Update

Withholding vulnerability details until operators upgrade is standard practice, but the absence of any severity signal leaves node operators to judge urgency on the vendor's word alone. The practical exposure sits with those running Lighthouse in production, where consensus-client issues can affect validator uptime and, in the worst case, network participation. The open question is how many operators complete the upgrade before disclosure, and whether the eventual details reveal a flaw that was actively exploitable in the interim.
