"value": "### Description\n\n`Symfony\\Component\\Mime\\Address` is 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.\n\nThe constructor accepts email addresses whose local-part (the part before `@`) is an RFC-5322 *quoted string* containing raw `\\r\\n` bytes — 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`'s `MAIL FROM:<...>` / `RCPT TO:<...>` protocol lines, turning the embedded CRLF into a new mail header and/or a new SMTP command.\n\n### Resolution\n\nThe `Address` constructor now rejects addresses containing line breaks.\n\nThe patch for this issue is available [here](https://github.com/symfony/symfony/commit/dc2dbd29211eb4ddc451373fa1374fb926e94604) for branch 5.4.\n\n### Credits\n\nWe would like to thank Claude Mythos Preview (via Project Glasswing) for reporting the issue and providing the fix."
