CVE-2026-3629
HighSummary
Wtyczka Import i eksport użytkowników i klientów dla WordPressa jest podatna na eskalację uprawnień we wszystkich wersjach do i włącznie z 1.29.7. Problem wynika z funkcji 'save_extra_user_profile_fields', która nieprawidłowo ogranicza, które klucze meta użytkownika mogą być aktualizowane przez pola profilu.
Risk Assessment
Atakujący bez uwierzytelnienia mogą zwiększyć swoje uprawnienia do Administratora, wysyłając spreparowane żądanie rejestracji, które ustawia klucz meta 'wp_capabilities'. To stwarza poważne ryzyko dla bezpieczeństwa systemu.
Recommendation
Zaleca się zaktualizowanie wtyczki do najnowszej wersji oraz wyłączenie opcji 'Pokaż pola w profilu', aby zminimalizować ryzyko eskalacji uprawnień.

Original NVD description (English source)
The Import and export users and customers plugin for WordPress is vulnerable to privilege escalation in all versions up to, and including, 1.29.7. This is due to the 'save_extra_user_profile_fields' function not properly restricting which user meta keys can be updated via profile fields. The 'get_restricted_fields' method does not include sensitive meta keys such as 'wp_capabilities'. This makes it possible for unauthenticated attackers to escalate their privileges to Administrator by submitting a crafted registration request that sets the 'wp_capabilities' meta key. The vulnerability can only be exploited if the "Show fields in profile" setting is enabled and a CSV with a wp_capabilities column header has been previously imported.
