    Summary: CakePHP: SmtpTransport vulnerable to CRLF header injection

    Details: ### Impact Custom mail headers added with `Message::setHeaders()` or `addHeaders()` do not have CRLF replaced allowing header injection if user controlled data is added to message headers without stripping CRLF bytes. ### Patches 5.3.7, 5.2.14, 5.1.9, 4.6.5, 4.5.12 contain fixes for this issue. ### Workarounds You can strip CRLF bytes from email header values before setting header values.
