PHPMailer before 5.2.27 and 6.x before 6.0.6 is vulnerable to an object injection attack.

PHPMailer before 5.2.27 and 6.x before 6.0.6 is vulnerable to an object injection attack.

PHPMailer versions prior to 6.0.6 and 5.2.27 are vulnerable to an object injection attack by passing phar:// paths into `addAttachment()` and other functions that may receive unfiltered local paths, possibly leading to RCE. See [this article](https://knasmueller.net/5-answers-about-php-phar-exploitation) for more info on this type of vulnerability. Mitigated by blocking the use of paths containing URL-protocol style prefixes such as `phar://`. Reported by Sehun Oh of cyberone.kr. ### Impact Object injection, possible remote code execution ### Patches Fixed in 6.0.6 and 5.2.27 ### Workarounds Validate and sanitise user input before using. ### References https://nvd.nist.gov/vuln/detail/CVE-2018-19296 ### For more information If you have any questions or comments about this advisory: * Open a private issue in [the PHPMailer project](https://github.com/PHPMailer/PHPMailer)
