A critical security vulnerability in the widely-used Nodemailer email library has been patched in its latest major version. The flaw, tracked as GHSA-c7w3-x93f-qmm8, allowed for arbitrary SMTP command injection, posing a severe risk to any application using the library to send mail. The vulnerability was triggered when...
A critical security vulnerability in the widely-used Nodemailer library allows for arbitrary SMTP command injection, posing a direct threat to email infrastructure integrity. The flaw, tracked as GHSA-c7w3-x93f-qmm8, is triggered when a custom `envelope` object containing a `size` property with CRLF characters (`\r\n`)...
A critical security vulnerability in the widely-used Nodemailer email-sending library has been patched in its new major version, v8. The flaw, tracked as GHSA-c7w3-x93f-qmm8, allowed for arbitrary SMTP command injection, posing a severe risk to any application using the library to send mail. This is not a theoretical w...
A critical security flaw in the widely-used Nodemailer library allowed attackers to silently hijack email delivery by injecting arbitrary SMTP commands. The vulnerability, tracked as GHSA-c7w3-x93f-qmm8, was present when a custom `envelope` object with a `size` property was passed to the `sendMail()` function. If this ...
A critical security vulnerability in the widely-used Nodemailer email library allows for arbitrary SMTP command injection. The flaw, tracked as GHSA-c7w3-x93f-qmm8, exists when a custom `envelope` object containing a `size` property is passed to the `sendMail()` function. If the `size` value includes carriage return an...
A critical security vulnerability in the widely-used Nodemailer library exposes countless applications to SMTP command injection. The flaw, tracked as GHSA-c7w3-x93f-qmm8, allows an attacker to inject arbitrary commands directly into the SMTP protocol stream, potentially compromising email servers and the applications ...
A critical security flaw in the SMTP transport's message builder allows attackers to inject arbitrary email headers by controlling the display name field. The vulnerability resides in the `formatAddress()` method, which interpolates the `addr.name` value into the `From:` and `To:` header lines without validating or str...
