CVE-2026-78296Network attack vectorHinoki check available

Unauthenticated identity spoofing via email verification bypass

Published Sep 17, 2026 · Updated Sep 19, 2026

Email verification bypass in WP ManageNinja LLC FluentAuth 2.1.2 and earlier allows remote attackers to spoof user identities. The CNA and referenced advisory do not identify the endpoint, identity-bearing input, or failed verification operation. No account or user interaction is required, but the published evidence establishes identity spoofing rather than administrator takeover.
