Summary
Ech0 to otwartoźródłowa platforma do publikacji, która przed wersją 4.2.8 pozwalała na przesyłanie dowolnego adresu URL przez parametr website_url w końcówce GET /api/website/title. Nie weryfikując hosta ani adresu IP, umożliwiała atakującym dostęp do wewnętrznych usług sieciowych oraz danych z metadanych chmurowych.
Risk Assessment
Brak uwierzytelnienia w tym końcowym punkcie stwarza ryzyko, że atakujący mogą uzyskać dostęp do wrażliwych danych i usług w sieci wewnętrznej organizacji. Może to prowadzić do wycieku danych oraz naruszenia bezpieczeństwa systemów.
Recommendation
Zaleca się aktualizację do wersji 4.2.8 lub nowszej, aby usunąć tę podatność. Dodatkowo, warto wprowadzić odpowiednie mechanizmy uwierzytelniania oraz weryfikacji adresów URL w aplikacji.

Original NVD description (English source)
Ech0 is an open-source, self-hosted publishing platform for personal idea sharing. Prior to 4.2.8, the GET /api/website/title endpoint accepts an arbitrary URL via the website_url query parameter and makes a server-side HTTP request to it without any validation of the target host or IP address. The endpoint requires no authentication. An attacker can use this to reach internal network services, cloud metadata endpoints (169.254.169.254), and localhost-bound services, with partial response data exfiltrated via the HTML <title> tag extraction This vulnerability is fixed in 4.2.8.
