CVE-2026-29199
HighSummary
phpBB w wersjach przed 3.3.16 jest podatny na atak typu Host Header Injection, co może prowadzić do zafałszowania linków do resetowania haseł. Gdy opcja force_server_vars jest wyłączona, nazwa hosta serwera może być pobrana z nagłówka HTTP Host, co jest używane do generowania URL do resetowania hasła.
Risk Assessment
Atakujący mogą manipulować nagłówkiem Host, co może skutkować wysyłaniem e-maili z linkami do resetowania haseł wskazującymi na domeny kontrolowane przez atakującego, co stwarza ryzyko przejęcia konta.
Recommendation
Zaleca się aktualizację phpBB do wersji 3.3.16 lub nowszej oraz włączenie walidacji nagłówków przez serwer webowy, aby zminimalizować ryzyko ataku.

Original NVD description (English source)
phpBB before 3.3.16 is vulnerable to Host Header Injection that can lead to password rest link poisoning. When force_server_vars is disabled, the servers hostname may be extracted from the HTTP Host header which is used to generate the password reset link URL. An attacker who can manipulate the Host header (e.g. through misconfigured host setup or missing header validation by the webserver) can cause password reset emails to contain a link pointing to an attacker-controlled domain, potentially leading to account takeover.
