| CVE | 概要 | ソース | CVSS 最大値 | EPSS（%） | 公開 | 更新 |
|---|---|---|---|---|---|---|
| CVE-2021-3603 | 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 validato | [email protected] | 8.1 | 0.76% | 2021-06-17 | 2024-11-21 |
| CVE-2021-34551 | PHPMailer before 6.5.0 on Windows allows remote code execution if lang_path is untrusted data and has a UNC pathname. | [email protected] | 8.1 | 2.11% | 2021-06-16 | 2024-11-21 |
| CVE-2020-36326 | PHPMailer 6.1.8 through 6.4.0 allows object injection through Phar Deserialization via addAttachment with a UNC pathname. NOTE: this is similar to CVE-2018-19296, but arose because 6.1.8 fixed a functionality problem in which UNC pathnames were always considered unreadable by PHPMailer, even in safe contexts. As an unintended side effect, this fix eliminated the code that blocked addAttachment exploitation. | [email protected] | 9.8 | 0.30% | 2021-04-28 | 2024-11-21 |
| CVE-2020-13625 | PHPMailer before 6.1.6 contains an output escaping bug when the name of a file attachment contains a double quote character. This can result in the file type being misinterpreted by the receiver or any mail relay processing the message. | [email protected] | 7.5 | 4.93% | 2020-06-08 | 2024-11-21 |
| CVE-2018-19296 | PHPMailer before 5.2.27 and 6.x before 6.0.6 is vulnerable to an object injection attack. | [email protected] | 8.8 | 1.47% | 2018-11-16 | 2024-11-21 |
| CVE-2017-11503 | PHPMailer 5.2.23 has XSS in the "From Email Address" and "To Email Address" fields of code_generator.php. | [email protected] | 6.1 | 2.94% | 2017-07-20 | 2026-05-13 |
| CVE-2017-5223 | An issue was discovered in PHPMailer before 5.2.22. PHPMailer's msgHTML method applies transformations to an HTML document to make it usable as an email message body. One of the transformations is to convert relative image URLs into attachments using a script-provided base directory. If no base directory is provided, it resolves to /, meaning that relative image URLs get treated as absolute local file paths and added as attachments. To form a remote vulnerability, the msgHTML method must be call | [email protected] | 5.5 | 2.92% | 2017-01-16 | 2026-05-13 |
| CVE-2016-10045 | The isMail transport in PHPMailer before 5.2.20 might allow remote attackers to pass extra parameters to the mail command and consequently execute arbitrary code by leveraging improper interaction between the escapeshellarg function and internal escaping performed in the mail function in PHP. NOTE: this vulnerability exists because of an incorrect fix for CVE-2016-10033. | [email protected] | 9.8 | 93.11% | 2016-12-30 | 2026-05-06 |
| CVE-2016-10033 KEV | The mailSend function in the 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. | [email protected] | 9.8 | 94.44% | 2016-12-30 | 2026-04-21 |
| CVE-2015-8476 | Multiple CRLF injection vulnerabilities in PHPMailer before 5.2.14 allow attackers to inject arbitrary SMTP commands via CRLF sequences in an (1) email address to the validateAddress function in class.phpmailer.php or (2) SMTP command to the sendCommand function in class.smtp.php, a different vulnerability than CVE-2012-0796. | [email protected] | 5.0 | 0.95% | 2015-12-16 | 2026-05-06 |
