Description
A regular expression denial of service (ReDoS) vulnerability exists in nodemailer versions before 6.9.9. This flaw occurs during email parsing when the attachDataUrls parameter is enabled or when processing embedded file attachments. An attacker can exploit this by sending specially crafted emails containing malicious data URLs or embedded attachments, causing the event loop to hang and resulting in a denial of service.
