TechOld LND Lightning nodes may face full-channel loss after delayed fix disclosure

LND has disclosed a channel-close flaw that, in a reproduced maximum-loss scenario, could put an entire channel balance at risk. A malicious peer could combine a one-block Bitcoin reorganization with an old revoked commitment transaction, preventing penalty transactions from being broadcast. The official fix is in LND 0.21.0, so standard releases below that version should be treated as unfixed unless patched independently.
