CVE-2026-12490
When a provide-xfr is given with a tls-auth-name, a secondary requesting a transfer should provide a client certificate with that name.
Impact
When a provide-xfr is given with a tls-auth-name, a secondary requesting a transfer should provide a client certificate with that name. However, no client certificate is needed when the request comes in over TLS over the regular tls-port (and not the tls-auth-port) or over over TCP over the regular port, when the other conditions of the provide-xfr rule match.
