AI-suggested
A security update fixing this vulnerability is available in Red Hat build of Quarkus version 3.33.3.SP2. Users should apply this update to remediate the issue. Since the vulnerability is fixed in this release, no additional mitigation steps are required beyond applying the official patch.
Description
A vulnerability in WildFly Elytron's password hashing and verification process causes input normalization using Unicode NFKC, which collapses fullwidth characters to ASCII equivalents. This reduces the effective password keyspace, allowing remote attackers to more easily guess passwords intended to include non-ASCII fullwidth characters by using ASCII-only dictionaries, potentially leading to unauthorized access.
