Bitcoin Lightning's Eclair receives second security patch in five days to counter malicious node exploits

Eclair software, which powers Bitcoin Lightning nodes for payment channels, released version 0.14.5 on Oct. 20 to fix new security flaws that malicious peers could exploit. This follows an Oct. 15 patch that blocked browser-based attacks via the administrative interface. Developers ACINQ urged operators to upgrade immediately, though the full extent of the risks and affected versions remains unspecified; no confirmed attacks or financial losses have been reported.
