CVE-2022-24968: TLS certificate validation error

February 12, 2022 (updated February 15, 2022)

In mellium.im/xmpp, an attacker capable of spoofing DNS TXT records can redirect a WebSocket connection request to a server under their control without causing TLS certificate verification to fail. This occurs because the wrong host name is selected during this verification.
