Description
Symfony\Component\Mime\Addressis the value-object every Symfony Mailer address (to/cc/bcc/from/reply-to) flows through; its constructor is documented as validating the address and throwing on invalid input, so developers treat it as a security boundary. The constructor accepts email addresses whose local-part (the part before@) is an RFC-5322 quoted string containing raw\r\nbytes — e.g."x\r\nBcc: attacker@evil"@example.com. The stored address is later emitted verbatim into (1) the rendered message headers and (2)SmtpTransport'sMAIL FROM:<...>/RCPT TO:<...>protocol lines, turning the embedded CRLF into a new mail header and/or a new SMTP command. ### Resolution TheAddressconstructor now rejects addresses containing line breaks. The patch for this issue is available here for branch 5.4. ### Credits We would like to thank Claude Mythos Preview (via Project Glasswing) for reporting the issue and providing the fix. - References
