BTCPay Temporarily Restricts Lightning Network Remote Access Due to LND Vulnerability
According to Cointelegraph, BTCPay Server has temporarily restricted public remote connections to Lightning Network nodes due to attackers exploiting a critical vulnerability in LND (Lightning Network Daemon) to steal node credentials and transfer funds. Version 2.4.2 has upgraded to LND 0.21.1 and automatically rotates macaroon credentials in standard installations. The project team reminds operators to check for abnormal payments, channel closures, and balance changes as soon as possible; if nodes are exposed via self-built reverse proxies, Tor services, or port forwarding, relevant credentials must also be manually replaced. Currently, Foundation and Citadel21 have reported node fund losses, but the specific scale of losses has not yet been disclosed.
