Most flagged Lightning nodes still lack year-old security fixes, preprint finds

TradingGain Newsroom·1h ago·02 Nov 2026, 08:55 UTC

A preprint dated October 21 estimates that 71% of an exposed group of LND nodes was still running affected software versions as of October 13. The security fixes for these versions are about a year old. For traders, the story highlights unresolved security risk on Bitcoin's Lightning Network, though it does not include direct price data.

Why it matters

• An estimated 71% of an exposed LND node group had not moved off affected release lines by October 13.
• The fixes have been available for about a year, so the gap is long-running rather than new.
• Security concerns on Bitcoin's Lightning Network could affect sentiment around Bitcoin infrastructure.

What to watch next

Watch for Lightning Network security updates, node upgrade announcements, or follow-up research that could change how serious this exposure looks.
