GHSA-5f37-gxvh-23v6
Remote code execution in PHPMailer
Quick fix
GHSA-5f37-gxvh-23v6 — phpmailer/phpmailer: upgrade to the fixed version with the command below.
composer require phpmailer/phpmailer:^5.2.18Details
### Impact The `mailSend` function in the default `isMail` transport in PHPMailer before 5.2.18 might allow remote attackers to pass extra parameters to the mail command and consequently execute arbitrary code via a \" (backslash double quote) in a crafted `Sender` property.
### Patches Fixed in 5.2.18
### Workarounds Filter and validate user input before passing it to internal functions.
