Core Lightning warned on October 2, 2026 that Bitcoin Lightning Network nodes running version 26.06.7 or earlier are being actively targeted; operators should upgrade immediately to 26.06.8 (released Sept 22, 2026) which patches a channel-closing flaw and other security issues. The development team has withheld some diagnostics to prevent reverse engineering of the fixes; no confirmed fund thefts have been disclosed but the situation is considered urgent.
