      <title>CVE-2026-107808 — Nginx UI: Authentication bypass: password login does not enforce a passkey-only second factor (2FA bypass)</title>
      <link>https://vulnerability.circl.lu/vuln/cve-2026-107808</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; 0xJacky nginx-ui&lt;/p&gt;
&lt;p&gt;Nginx UI is a web user interface for the Nginx web server. From 2.0.0 until 2.5.0, POST /api/login checks EnabledOTP but does not require a WebAuthn assertion when EnabledPasskey is true and no TOTP secret is configured. A passkey-only account is therefore issued a session after password verification, despite Enabled2FA reporting that the account has a second factor. An attacker who obtains the password can take over the account and reach administrative functionality without the registered passkey. This issue is fixed in version 2.5.0.&lt;/p&gt;</description>
