Core Lightning warns of vulnerabilities, urges update

This is a reminder that Lightning node security remains a live operational issue, not just a theoretical one. The advisory's emphasis on offline mode suggests the vulnerabilities could be actively exploitable, meaning node operators who delay patching are making a risk calculation with real consequences for their channels and funds. The broader implication is that the network's resilience depends on how quickly operators respond to such warnings. Whether the patch fully closes the gaps and whether other implementations face similar scrutiny are the key things to watch.
