CVE-2026-19611

A flaw was found in WildFly Elytron. Password hashing and verification normalize input with Unicode NFKC, which can collapse fullwidth characters to ASCII equivalents. A remote attacker can more easily guess affected passwords by using an ASCII-only dictionary against accounts whose passwords wer...

CVE-2026-73420 NextAuth.js: Email normalizer validates the address before Unicode normalization, allowing a homoglyph @ bypass

NextAuth.js provides authentication for Next.js. Prior to @auth/core 0.41.3 and next-auth 4.24.15 and 5.0.0-beta.32, the defaultNormalizer used by the email and magic-link sign-in flow validates an address before applying Unicode normalization. An address can contain a Unicode character such as...

Astra Linux – Vulnerability in Pypy

Python versions 2.7.x through 2.7.16, and 3.x through 3.7.2 are affected by improper handling of Unicode encoding with an incorrect netloc during NFKC normalization. The impact is information disclosure—credentials, cookies, etc., that are cached against a given hostname. The affected components...
