 ## Why you might need it
-Many PHP developers need to send email from their code. The only PHP function that supports this is [`mail()`](https://www.php.net/manual/en/function.mail.php). However, it does not provide any assistance for making use of popular features such as encryption, authentication, HTML messages, and attachments.

However, it does not provide any assistance for making use of popular features such as encryption, authentication, HTML messages, and attachments.
 
-Formatting email correctly is surprisingly difficult. There are myriad overlapping RFCs, requiring tight adherence to horribly complicated formatting and encoding rules – the vast majority of code that you'll find online that uses the `mail()` function directly is just plain wrong!
+Formatting email correctly is surprisingly difficult. There are myriad overlapping (and conflicting) standards, requiring tight adherence to horribly complicated formatting and encoding rules – the vast majority of code that you'll find online that uses the `mail()` function directly is just plain wrong, if not unsafe!
-*Please* don't be tempted to do it yourself – if you don't use PHPMailer, there are many other excellent libraries that you should look at before rolling your own. Try [SwiftMailer](https://swiftmailer.symfony.com/), [Zend/Mail](https://zendframework.github.io/zend-mail/), [ZetaComponents](https://github.com/zetacomponents/Mail) etc.
 
-The PHP `mail()` function usually sends via a local mail server, typically fronted by a `sendmail` binary on Linux, BSD, and macOS platforms, however, Windows usually doesn't include a local mail server; PHPMailer's integrated SMTP implementation allows email sending on Windows platforms without a local mail server.

Be aware though, that the `mail()` function should be avoided when possible; it's both faster and [safer](https://exploitbox.io/paper/Pwning-PHP-Mail-Function-For-Fun-And-RCE.html) to use SMTP to localhost.

 ## Installation & loading
 PHPMailer is available on [Packagist](https://packagist.org/packages/phpmailer/phpmailer) (using semantic versioning), and installation via [Composer](https://getcomposer.org) is the recommended way to install PHPMailer. Just add this line to your `composer.json` file:
 
 ```json

 ## Legacy versions
-PHPMailer 5.2 (which is compatible with PHP 5.0 - 7.0) is no longer being supported, even for security updates. You will find the latest version of 5.2 in the [5.2-stable branch](https://github.com/PHPMailer/PHPMailer/tree/5.2-stable). If you're using PHP 5.5 or later (which you should be), switch to the 6.x releases.

If you're using PHP 5.5 or later (which you should be), switch to the 6.x releases.
 
 ### Upgrading from 5.2
 The biggest changes are that source files are now in the `src/` folder, and PHPMailer now declares the namespace `PHPMailer\PHPMailer`. This has several important effects – [read the upgrade guide](https://github.com/PHPMailer/PHPMailer/tree/master/UPGRADING.md) for more details.
 
 ### Minimal installation
-While installing the entire package manually or with Composer is simple, convenient, and reliable, you may want to include only vital files in your project. At the very least you will need [src/PHPMailer.php](https://github.com/PHPMailer/PHPMailer/tree/master/src/PHPMailer.php). If you're using SMTP, you'll need [src/SMTP.php](https://github.com/PHPMailer/PHPMailer/tree/master/src/SMTP.php), and if you're using POP-before SMTP, you'll need [src/POP3.php](https://github.com/PHPMailer/PHPMailer/tree/master/src/POP3.php). You can skip the [language](https://github.com/PHPMailer/PHPMailer/tree/master/language/) folder if you're not showing errors to users and can make do with English-only errors. If you're using XOAUTH2 you will need [src/OAuth.php](https://github.com/PHPMailer/PHPMailer/tree/master/src/OAuth.php) as well as the Composer dependencies for the services you wish to authenticate with. Really, it's much easier to use Composer!

Their filenames contain [ISO 639-1](http://en.wikipedia.org/wiki/ISO_639-1) language code for the translations, for example `fr` for French.

 If the documentation doesn't cover what you need, search the [many questions on Stack Overflow](http://stackoverflow.com/questions/tagged/phpmailer), and before you ask a question about "SMTP Error: Could not connect to SMTP host.", [read the troubleshooting guide](https://github.com/PHPMailer/PHPMailer/wiki/Troubleshooting).
 
 ## Tests
-There is a PHPUnit test script in the [test](https://github.com/PHPMailer/PHPMailer/tree/master/test/) folder. PHPMailer uses PHPUnit 4.8 - we would use 5.x but we need to run on PHP 5.5.
+[PHPMailer tests](https://github.com/PHPMailer/PHPMailer/tree/master/test/) use PHPUnit 9, with [a polyfill](https://github.com/Yoast/PHPUnit-Polyfills) to let 9-style tests run on older PHPUnit and PHP versions.

+Please disclose any vulnerabilities found responsibly – report security issues to the maintainers privately.
 
-PHPMailer versions prior to 5.2.22 (released January 9th 2017) have a local file disclosure vulnerability, [CVE-2017-5223](https://web.nvd.nist.gov/view/vuln/detail?vulnId=CVE-2017-5223). If content passed into `msgHTML()` is sourced from unfiltered user input, relative paths can map to absolute local file paths and added as attachments. Also note that `addAttachment` (just like `file_get_contents`, `passthru`, `unlink`, etc) should not be passed user-sourced params either! Reported by Yongxiang Li of Asiasecurity.

 # Security notices relating to PHPMailer
 
-Please disclose any vulnerabilities found responsibly - report any security problems found to the maintainers privately.
+Please disclose any security issues or vulnerabilities found through [Tidelift's coordinated disclosure system](https://tidelift.com/security) or to the maintainers privately.
+
+PHPMailer 6.4.1 and earlier contain a vulnerability that can result in untrusted code being called (if such code is injected into the host project's scope by other means). If the `$patternselect` parameter to `validateAddress()` is set to `'php'` (the default, defined by `PHPMailer::$validator`), and the global namespace contains a function called `php`, it will be called in preference to the built-in validator of the same name. Mitigated in PHPMailer 6.5.0 by denying the use of simple strings as validator function names. Recorded as [CVE-2021-3603](https://web.nvd.nist.gov/view/vuln/detail?vulnId=CVE-2021-3603). Reported by [Vikrant Singh Chauhan](mailto:vi@hackberry.xyz) via [huntr.dev](https://www.huntr.dev/).
+
+PHPMailer versions 6.4.1 and earlier contain a possible remote code execution vulnerability through the `$lang_path` parameter of the `setLanguage()` method. If the `$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 persuade the server to load a file from that UNC path, a script file under their control may be executed. This vulnerability only applies to systems that resolve UNC paths, typically only Microsoft Windows.
+PHPMailer 6.5.0 mitigates this by no longer treating translation files as PHP code, but by parsing their text content directly. This 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. Recorded as [CVE-2021-34551](https://web.nvd.nist.gov/view/vuln/detail?vulnId=CVE-2021-34551). Reported by [Jilin Diting Information Technology Co., Ltd](https://listensec.com) via Tidelift.
+
+PHPMailer versions between 6.1.8 and 6.4.0 contain a regression of the earlier CVE-2018-19296 object injection vulnerability as a result of [a fix for Windows UNC paths in 6.1.8](https://github.com/PHPMailer/PHPMailer/commit/e2e07a355ee8ff36aba21d0242c5950c56e4c6f9). Recorded as [CVE-2020-36326](https://web.nvd.nist.gov/view/vuln/detail?vulnId=CVE-2020-36326). Reported by Fariskhi Vidyan via Tidelift. 6.4.1 fixes this issue, and also enforces stricter checks for URL schemes in local path contexts.
+
+PHPMailer versions 6.1.5 and earlier contain an output escaping bug that occurs in `Content-Type` and `Content-Disposition` when filenames passed into `addAttachment` and other methods that accept attachment names contain double quote characters, in contravention of RFC822 3.4.1. No specific vulnerability has been found relating to this, but it could allow file attachments to bypass attachment filters that are based on matching filename extensions. Recorded as [CVE-2020-13625](https://web.nvd.nist.gov/view/vuln/detail?vulnId=CVE-2020-13625). Reported by Elar Lang of Clarified Security.
 
 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. Recorded as [CVE-2018-19296](https://web.nvd.nist.gov/view/vuln/detail?vulnId=CVE-2018-19296). 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.
