Phar object injection in PHPMailer
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 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.
