Despite all the craziness going on, I would like to personally shake hands with all of you, my fellow schizos, still stacking these internet coins with our private keys ๐Ÿค God bless us all and our devices and forks and nodes and btcpayservers
Btcpayserver exploit explained: The old check only refused Basic auth if the user had FIDO2 credentials (a hardware security key). If you secured your account with TOTP (Google Authenticator etc.), Fido2Credentials.Any() was false, so the API accepted username+password and never asked for the TOTP code. An attacker who obtained your password (reuse, phishing, a leak, brute force) could authenticate straight into Greenfield and skip the second factor entirely, then call spend endpoints.
The btcpayserver exploit looks related to the paypayment request endpoint They applied a rate limiter to it I guess you can just blast this endpoint and at some point auth fails or something? Not sure how this can be exploited Anyway be sure to update no matter what
