    CVE-2021-3603 (GCVE-0-2021-3603)

    Vulnerability from cvelistv5 – Published: 2021-06-17 12:09 – Updated: 2024-08-03 17:01
    VLAI
    Title
    Inclusion of Functionality from Untrusted Control Sphere in PHPMailer/PHPMailer
    Summary
    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.
    Severity
    8.1 (High)
