Summary
LinkAce to samodzielnie hostowany archiwum do zbierania linków do stron internetowych. Wersje przed 2.5.3 blokują bezpośrednie żądania do prywatnych adresów IP, ale nadal wykonują żądania po stronie serwera do zasobów dostępnych tylko wewnętrznie, gdy te zasoby są odwoływane przez wewnętrzną nazwę hosta.
Risk Assessment
Umożliwia to uwierzytelnionemu użytkownikowi wywołanie żądań po stronie serwera do wewnętrznych usług, które są dostępne dla serwera LinkAce, ale nie są bezpośrednio dostępne dla użytkownika zewnętrznego. Może to prowadzić do nieautoryzowanego dostępu do wrażliwych zasobów.
Recommendation
Zaleca się aktualizację do wersji 2.5.3 lub nowszej, aby załatać tę podatność i zminimalizować ryzyko nieautoryzowanego dostępu do wewnętrznych usług.

Original NVD description (English source)
LinkAce is a self-hosted archive to collect website links. Versions prior to 2.5.3 block direct requests to private IP literals, but still performs server-side requests to internal-only resources when those resources are referenced through an internal hostname. This allows an authenticated user to trigger server-side requests to internal services reachable by the LinkAce server but not directly reachable by an external user. Version 2.5.3 patches the issue.
