Upstream source description

BTCPay Server before 2.4.2, including 2.4.2 release candidates, contains an information disclosure vulnerability that allows unauthenticated remote attackers to retrieve .macaroon credential files for an LND (Lightning Network Daemon) node. Attackers can use the exposed macaroon to gain full control of the LND node, including moving funds, resulting in theft of funds from affected deployments.
