SmarterTools SmarterMail 16.x before build 6985 has hardcoded secret keys. An unauthenticated attacker could access other users’ emails and file attachments. It was also possible to interact with mailing lists.

SmarterTools SmarterMail before 13.3.5535 was vulnerable to stored XSS by bypassing the anti-XSS mechanisms.
