Improper Handling of Alternate Encoding

Overview Affected versions of this package are vulnerable to Improper Handling of Alternate Encoding in its password normalization, which applies Unicode NFKC compatibility normalization before hashing and so folds fullwidth and other compatibility characters to their ASCII equivalents. An attack...

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 wer...
