BTCPay Server 1.3.0 through 1.5.3 allows a remote attacker to obtain sensitive information when a public Point of Sale app is exposed. The sensitive information, found in the HTML source code, includes the xpub of the store. Also, if the store isn't using the internal lightning node, the credentials of a lightning node are exposed.
Add your gear to cvedb and we'll alert you only when btcpayserver ships something exploited.
