Detailsinfo

A vulnerability, which was classified as critical, was found in Nodemailer up to 9.0.0. Affected is an unknown functionality of the component Raw Option Handler. The manipulation of the argument path/href with an unknown input leads to a server-side request forgery vulnerability. CWE is classifying the issue as CWE-918.
