reports:
SMTP Command Injection in Appointment Emails via Newlines: as newlines
and special characters are not sanitized in the email value in the JSON
request, a malicious attacker can inject newlines to break out of the
RCPT TO:<BOOKING USER'S EMAIL> SMTP command and begin injecting
arbitrary SMTP commands.
