CVE-2026-19611Published 26 days ago. NVD backfills CPE data for days or weeks after publication, and OSV and the exploit indexes lag too. Scope and status here may change.
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.
CWE-173
No public exploit
Nothing published shows this CVE being exploited, which is not the same as ruling it out.
CVSS E:U
In RASP's scope with an upstream fix path, but nobody has published a working exploit. That is a statement about what has been published, not a finding that the defect is unreachable or unimportant.
| Decided by | no-exploit-published : A published working exploit for this candidate, not only a proof of concept, a forecast, or nothing at all |
|---|---|
| Finding | This CVE is not listed in CISA KEV, CISA Vulnrichment records no active exploitation, and no reviewed exploit catalogue carries an entry for it. Nobody has published something a stranger can run, so it is not a candidate for a rule ahead of the ones where somebody has; an upstream fix path does exist, so the remediation half of the candidacy still holds. This is a statement about what has been published, not about whether the defect is reachable or serious. |

1 metric
VRT selects the newest version's highest entry and
publishes it as cvssScore, newest rather than largest because scores are not comparable
across versions, and highest rather than first because the first entry is frequently a CNA placeholder
scoring 0.0 over NVD's own analysis.
