Unpatched PHPMailer Vulnerability

PHPMailer is a popular open-source library used for sending emails in PHP applications. The vulnerability allows attackers to inject malicious code into email bodies, potentially leading to remote code execution and sensitive data exposure.

You're affected if you use PHPMailer version 5.2.0 or earlier. Check with: grep -r "PHPMailer" phpMailer.php

Note: This is a relatively niche software, so if you don't recognize the name, you're probably not affected. However, if you use PHP applications that rely on email functionality, this vulnerability might still be relevant.

1. Upgrade to PHPMailer version 5.2.3 or later from the official GitHub repository: https://github.com/PHPMailer/PHPMailer/releases/tag/v5.2.3
2. If immediate upgrade isn't possible, consider using a different email library or implementing additional security measures.
