If the `$lang_path` parameter is passed unfiltered from user input, it can be set to [a UNC path](https://docs.microsoft.com/en-us/dotnet/standard/io/file-path-formats#unc-paths), and if an attacker is also able to create a remote mount on the server that the UNC path points to, a script file under their control may be executed. \n\n### Impact\nArbitrary code may be run by a remote attacker under the web server or PHP process running on Window hosts.\n\n### Patches\nMitigated in PHPMailer 6.5.0 by no longer treating translation files as PHP code, but by parsing their text content directly.\nThis approach avoids the possibility of executing unknown code while retaining backward compatibility. This isn't ideal, so the current translation format is deprecated and will be replaced in the next major release.\n\n### Workarounds\nAny of:\n* Ensure that calling code does not pass unfiltered user-supplied data to the `$lang_path` parameter of the `setLanguage()` method.\n* Block or filter the use of unknown UNC paths in this parameter (or altogether).\n* Ensure that unauthorised users do not have the ability to read from unknown remote servers via UNC paths.\n* Run on an OS that does not support UNC paths\n\n###

"summary": "Object injection in PHPMailer/PHPMailer\n### Impact\nThis is a reintroduction of an earlier issue (CVE-2018-19296) by an unrelated bug fix in PHPMailer 6.1.8. An external file may be unexpectedly executable if it is used as a path to an attachment file via PHP's support for `.phar` files`. Exploitation requires that an attacker is able to provide an unfiltered path to a file to attach, or to trick calling code into generating one. See [this article](https://knasmueller.net/5-answers-about-php-phar-exploitation) for more info.\n\n### Patches\nThis issue was patched in the PHPMailer 6.4.1 release. This release also implements stricter filtering for attachment paths; paths that look like *any* kind of URL are rejected.\n\n### Workarounds\nValidate paths to loaded files using the same pattern as used in [`isPermittedPath()`](https://github.com/PHPMailer/PHPMailer/blob/master/src/PHPMailer.php#L1815) before using them in *any* PHP file function, such as `file_exists`. This method can't be used directly because it is protected, but you can implement the same thing in calling code. Note that this should be applied to *all* user-supplied paths passed into such functions; it's not a problem specific to PHPMailer.\n\n### Credit\nThis issue was found by Fariskhi Vidyan, reported and

it will be called in default configuration as when no validation scheme is provided, the default scheme's callable `php` was being called. If an attacker is able to inject such a function into the application (a much bigger issue), it will be called whenever an email address is validated, such as when calling `validateAddress()`.\n\n### Impact\nLow impact – exploitation requires that an attacker can already inject code into an application, but it provides a trigger pathway.\n\n### Patches\nThis is patched in PHPMailer 6.5.0 by denying the use of simple strings as validator function names, which is a very minor BC break.\n\n### Workarounds\nInject your own email validator function.\n\n### References\nReported by [Vikrant
