SCA: security update for phpmailer/phpmailer (GHSA-77mr-wc79-m8j3)
high Tenable Cloud Security Plugin ID 411907
Description
There are packages installed that are affected by a vulnerability referenced in the following CVE:- 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.
