CVE-2026-33399
HighSummary
Wallos to otwartoźródłowy, samodzielny tracker subskrypcji. W wersjach przed 4.7.0 poprawka dotycząca SSRF zastosowana w wersji 4.6.2 była niekompletna, co pozwalało uwierzytelnionym użytkownikom na zapisanie wewnętrznego adresu IP jako URL powiadomienia.
Risk Assessment
Organizacja może być narażona na ataki SSRF, co może prowadzić do nieautoryzowanego dostępu do wewnętrznych zasobów sieciowych. Wykorzystanie tej podatności może skutkować ujawnieniem wrażliwych danych lub naruszeniem bezpieczeństwa systemu.
Recommendation
Zaleca się aktualizację do wersji 4.7.0, aby załatać tę podatność. Należy również przeprowadzić audyt istniejących konfiguracji powiadomień w celu zidentyfikowania potencjalnych zagrożeń.

Original NVD description (English source)
Wallos is an open-source, self-hostable personal subscription tracker. Prior to version 4.7.0, the SSRF fix applied in version 4.6.2 for CVE-2026-30839 and CVE-2026-30840 is incomplete. The validate_webhook_url_for_ssrf() protection was added to the test* notification endpoints but not to the corresponding save* endpoints. An authenticated user can save an internal/private IP address as a notification URL, and when the cron job sendnotifications.php executes, the request is sent to the internal IP without any SSRF validation. This issue has been patched in version 4.7.0.
