Technical details

The /callback/email endpoint in EmailController is mapped as anonymously accessible due to a blanket .requestMatchers("/callback/**").anonymous() security configuration, allowing unauthenticated POST requests. Attackers can invoke sendEmail() with caller-supplied subject, content, and recipient address (tos parameter), which are passed directly to MailUtil.sendMail() without validation. The vulnerability requires only network access and results in email spoofing from the operator's configured SMTP account.
