CVE-2026-19611: Wildfly-elytron: org.wildfly.security/wildfly-elytron-password-impl: wildfly-elytron: password keyspace reduction via nfkc fullwidth folding

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 were intended to include those non-ASCII characters, leading to unauthorized access.
