CVE-2026-42606
AzuraCast is a self-hosted, all-in-one web radio management suite. Prior to version 0.23.6, the ApplyXForwarded middleware unconditionally trusts the client-supplied X-Forwarded-Host HTTP header with no trusted proxy allowlist. An unauthenticated attacker can poison the password reset URL sent to any user by injecting this header when triggering the forgot-password flow. When the victim clicks the poisoned link, their reset token is exfiltrated to the attacker's server. The attacker then uses the token on the real instance to reset the victim's password and destroy their 2FA configuration, achieving full account takeover. This issue has been patched in version 0.23.6.
CVSS

Antes de la versión 0.23.6, el middleware ApplyXForwarded confía incondicionalmente en el encabezado HTTP X-Forwarded-Host proporcionado por el cliente, sin una lista de permitidos de proxies de confianza. Un atacante no autenticado puede envenenar la URL de restablecimiento de contraseña enviada a cualquier usuario inyectando este encabezado al activar el flujo de 'olvidé mi contraseña'. Cuando la víctima hace clic en el enlace envenenado, su token de restablecimiento es exfiltrado al servidor del atacante. El atacante luego usa el token en la instancia real para restablecer la contraseña de la víctima y destruir su configuración de 2FA, logrando una toma de control total de la cuenta. Este problema ha sido parcheado en la versión 0.23.6."
