CVE-2021-3603 is fixed in libphp-phpmailer on 1 platform, first by libphp-phpmailer 6.0.6-0.1ubuntu0.1~esm1, released June 17, 2021. It is not reported as exploited. Patch Radar priority: Routine.
PHPMailer 6.4.1 and earlier contain a vulnerability that can result in untrusted code being called (if such code is injected into the host project's scope by other means). If the $patternselect parameter to validateAddress() is set to 'php' (the default, defined by PHPMailer::$validator), and the global namespace contains a function called php, it will be called in preference to the built-in validator of the same name. Mitigated in PHPMailer 6.5.0 by denying the use of simple strings as validator function names.
