      <title>CVE-2026-84479 — WWBN AVideo Authentication Bypass via User-Agent Header</title>
      <link>https://vulnerability.circl.lu/vuln/cve-2026-84479</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; WWBN AVideo&lt;/p&gt;
&lt;p&gt;WWBN AVideo (current e01e41ecc and earlier) makes three login-time security controls depend solely on the client-supplied User-Agent header. The isAVideoEncoder()/isAVideoMobileApp() checks match HTTP_USER_AGENT against a hardcoded literal (&amp;#34;AVideoEncoder&amp;#34;/&amp;#34;AVideoMobileApp&amp;#34;) with no IP check or shared secret. An attacker who submits valid credentials and sets User-Agent: AVideoEncoder bypasses two-factor authentication, skips brute-force captcha escalation, and avoids being recorded in the login/device audit history. No patch is available at the time of publication.&lt;/p&gt;</description>
