CVE-2022-39389 is a high-severity flaw (CVSS 8.2) affecting btcd, lightning network daemon. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

Lightning Network Daemon (lnd) is an implementation of a lightning bitcoin overlay network node. All lnd nodes before version `v0.15.4` are vulnerable to a block parsing bug that can cause a node to enter a degraded state once encountered. In this degraded state, nodes can continue to make payments and forward HTLCs, and close out channels. Opening channels is prohibited, and also on chain transaction events will be undetected. This can cause los
