What is CVE-2016-10045?

The isMail transport in PHPMailer versions prior to 5.2.20 could allow attackers to execute arbitrary code remotely by injecting additional parameters into the mail command. This flaw arises from improper handling of arguments by the escapeshellarg function in conjunction with internal escape mechanisms of the PHP mail function. The issue persists despite earlier patches designed to address similar vulnerabilities, presenting a significant risk to applications that rely on PHPMailer for email functionalities.
