How this page is checked

StackPrism asks OSV.dev which advisories affect exactly nodemailer 3.0.2, merges duplicates filed under several ids, and ranks them with CISA’s Known Exploited Vulnerabilities list and FIRST EPSS. Release dates and deprecation come from deps.dev and npm. No AI writes this page: every sentence comes from that data, refreshed every few hours.

Last checked against npm, OSV.dev, deps.dev, CISA KEV and FIRST EPSS (didn’t answer). Findings from that source may be missing; this page refreshes soon.
