A newly disclosed unfunded-channel flaw could leave Eclair, a Bitcoin Lightning implementation, crashing repeatedly without an attacker spending BTC on-chain. The flaw affected reachable nodes running v0.14.0 and earlier, with saved channel records making a restart insufficient to restore service. Researcher Erick Cestari published the persistent-crash finding on September 30 and explained it alongside a separate denial-of-service bug in an October 1 developer post. Both were fixed in v0.14.1, released in July, before the public disclosures. ACINQ now recommends the later v0.14.3 security release for separate vulnerabilities.
