CVE-2025-4279
HighSummary
Wtyczka External image replace dla WordPressa jest podatna na nieautoryzowane przesyłanie plików z powodu braku walidacji typu pliku w funkcji 'external_image_replace_get_posts::replace_post' we wszystkich wersjach do 1.0.8 włącznie. Umożliwia to uwierzytelnionym atakującym z uprawnieniami na poziomie co najmniej 'contributor' przesyłanie dowolnych plików na serwer dotkniętej witryny.
Risk Assessment
Podatność ta stwarza ryzyko zdalnego wykonania kodu, co może prowadzić do poważnych naruszeń bezpieczeństwa w organizacji. Atakujący mogą wykorzystać tę lukę do przejęcia kontroli nad serwerem.
Recommendation
Zaleca się aktualizację wtyczki do najnowszej wersji, aby usunąć tę podatność. Dodatkowo, warto wprowadzić dodatkowe mechanizmy zabezpieczeń, takie jak ograniczenie uprawnień użytkowników oraz monitorowanie przesyłanych plików.

Original NVD description (English source)
The External image replace plugin for WordPress is vulnerable to arbitrary file uploads due to missing file type validation in the 'external_image_replace_get_posts::replace_post' function in all versions up to, and including, 1.0.8. This makes it possible for authenticated attackers, with contributor-level and above permissions, to upload arbitrary files on the affected site's server which may make remote code execution possible.
