Summary
Ech0 to otwartoźródłowa platforma do publikacji, która przed wersją 4.2.8 implementowała podgląd linków poprzez nieautoryzowany dostęp do API. Wykorzystanie tej funkcji pozwalało atakującym na wysyłanie dowolnych URL-i, co prowadziło do niebezpiecznego zachowania serwera.
Risk Assessment
Organizacja może być narażona na ataki typu Server-Side Request Forgery (SSRF), co może prowadzić do wycieku danych lub nieautoryzowanego dostępu do zasobów wewnętrznych. Atakujący mogą wykorzystać tę podatność do manipulacji serwerem i uzyskania dostępu do wrażliwych informacji.
Recommendation
Zaleca się aktualizację do wersji 4.2.8 lub nowszej, aby usunąć tę podatność. Dodatkowo, warto wdrożyć mechanizmy autoryzacji oraz filtrowania URL-i w celu zwiększenia bezpieczeństwa aplikacji.

Original NVD description (English source)
Ech0 is an open-source, self-hosted publishing platform for personal idea sharing. Prior to 4.2.8, Ech0 implements link preview (editor fetches a page title) through GET /api/website/title. That is legitimate product behavior, but the implementation is unsafe: the route is unauthenticated, accepts a fully attacker-controlled URL, performs a server-side GET, reads the entire response body into memory (io.ReadAll). There is no host allowlist, no SSRF filter, and InsecureSkipVerify: true on the outbound client. Anyone who can reach the instance can force the Ech0 server to open HTTP/HTTPS URLs of their choice as seen from the server’s network position (Docker bridge, VPC, localhost from the process view). This vulnerability is fixed in 4.2.8.
