CyberRota Analysis

AI-Generated

Nodemailer versions prior to 8.0.9 are vulnerable due to inadequate sanitization of carriage return and line feed characters in list comment fields, enabling attackers to inject arbitrary message headers. This can lead to manipulation of RFC822 messages, potentially altering mail client behavior and compromising message integrity. Organizations using affected versions of Nodemailer should prioritize updating to mitigate risks associated with email spoofing and header injection attacks.

Original NVD Description

Nodemailer before 8.0.9 fails to sanitize carriage return and line feed characters in list comment fields, allowing attackers to inject arbitrary message headers. An attacker with control over list.*.comment parameters can inject CRLF sequences to create additional headers in generated RFC822 messages, altering mail client behavior and message semantics.
