CVE-2026-33401

  3. CVE-2026-33401
Wallos is an open-source, self-hostable personal subscription tracker. Prior to version 4.7.0, the patch introduced in commit e8a513591 (CVE-2026-30840) added SSRF protection to notification test endpoints but left three additional attack surfaces unprotected: the AI Ollama host parameter, the AI recommendations endpoint, and the notification cron job. An authenticated user can reach internal network services, cloud metadata endpoints (AWS IMDSv1, GCP, Azure IMDS), or localhost-bound services by supplying a crafted URL to any of these endpoints. This issue has been patched in version 4.7.0.

Summary
  • (es) Wallos es un rastreador de suscripciones personales de código abierto y autoalojable. Antes de la versión 4.7.0, el parche introducido en el commit e8a513591 (CVE-2026-30840) añadió protección SSRF a los puntos finales de prueba de notificación, pero dejó tres superficies de ataque adicionales desprotegidas: el parámetro de host de AI Ollama, el punto final de recomendaciones de AI y el trabajo cron de notificación. Un usuario autenticado puede alcanzar servicios de red internos, puntos finales de metadatos en la nube (AWS IMDSv1, GCP, Azure IMDS) o servicios vinculados a localhost al proporcionar una URL manipulada a cualquiera de estos puntos finales. Este problema ha sido parcheado en la versión 4.7.0.
