0 CVE-2026-73420 is a critical vulnerability in NextAuth.js affecting the email and magic-link sign-in flow. The default email address normalizer validates the address before applying Unicode normalization, allowing an attacker to exploit Unicode characters that canonicalize to ASCII at-signs. This can cause a misrouting of passwordless sign-in links to attacker-controlled addresses, enabling unauthorized sign-in without victim interaction. The issue is fixed in @auth/core 0.41.3, next-auth 4.24.15, and 5.0.0-beta.32. Join the discussion | CVE Database V5 | 08/13/2026, 22:04:15 UTC Added: 08/13/2026, 22:12:00 UTC |
