A Bitcoin Lightning flaw could send a node’s entire balance straight to miners
ACINQ patched three vulnerabilities in its Eclair Bitcoin Lightning software that could allow malicious peers to drain, lock, or redirect node funds. The most severe flaw could cause a node's entire local channel balance to be lost to miner fees during a cooperative close. ACINQ recommended users upgrade to the latest version, Eclair 0.14.3, to mitigate these risks.
