Older Lightning nodes may face full-channel wipeout before LND protection arrives

Older Lightning Network nodes may remain exposed to a full-channel wipeout because the official LND protection was introduced later than previously disclosed, according to CryptoSlate. Repository history places the fix in LND version 0.21.0. As a result, earlier standard releases may still be vulnerable unless operators applied a separate patch. The finding affects the timing and scope of protection for users running older LND software, rather than indicating that all Lightning nodes are affected. CryptoSlate reported the issue on Aug. 26, 2026, citing the project’s repository history. Operators and market participants tracking Lightning infrastructure should distinguish between nodes upgraded to version 0.21.0 and older installations that may not have received an independent remediation. The report does not provide additional details on the underlying issue or quantify the number of potentially exposed channels.
