CVE-2026-45067: ### Description `Symfony\Component\Mime\Address` is the value-object every Symfony Mailer address (to/cc/bcc/from/reply

A vulnerability in Symfony Mailer's Address class allowed attackers to inject email headers and SMTP commands (the protocol used to send emails) by embedding line break characters in email addresses. The constructor was supposed to validate addresses but failed to catch addresses with hidden `\r\n` bytes in the local-part (the text before the `@` symbol), which could be exploited to add unauthorized recipients or headers when the email was sent.
