CVE-2026-31283
CriticalSummary
W Totara LMS w wersji 19.1.5 i wcześniejszych, API do resetowania hasła nie wprowadza limitu liczby prób dla docelowego adresu e-mail, co może być wykorzystane do ataku typu Email Bombing. Dodatkowo, konfiguracja pwresettime domyślnie wynosi 30 minut, a aktywacja flagi PWRESET_STATUS_ALREADYSENT zapobiega wysyłaniu kolejnych wiadomości o resetowaniu hasła dla danego adresu e-mail.
Risk Assessment
Brak limitu prób dla resetowania hasła może prowadzić do przeciążenia systemu oraz zakłócenia działania usługi, co może wpłynąć na dostępność i reputację organizacji.
Recommendation
Zaleca się wprowadzenie limitu prób dla API resetowania hasła oraz monitorowanie aktywności związanej z tym procesem, aby zminimalizować ryzyko ataków typu Email Bombing.

A vulnerability in FalkorDB before 4.18.4 causes a heap-based out-of-bounds read in the BufferSerializerIOv2_ReadBuffer function. A remote attacker who can issue Redis replication commands (e.g., against an instance with no password) can send a crafted RDB stream with a sub-buffer length field exceeding the remaining buffer size. The only bounds check is an ASSERT(), which is compiled out in release builds, so memcpy() reads past the end of the heap allocation.
- CVE-2026-5759Critical
A double free and use-after-free vulnerability in the RdbLoadDeletedNodes function of the RDB graph decoders in FalkorDB before 4.18.1. A remote attacker who can issue Redis replication commands can send a crafted RDB stream where the deleted-nodes buffer length is not a multiple of sizeof(NodeID). The length check relies on ASSERT(), which is compiled out in release builds, so the function continues after freeing the buffer, reading it and freeing it a second time.

Original NVD description (English source)
In Totara LMS v19.1.5 and before, the forgot password API does not implement rate limiting for the target email address. which can be used for an Email Bombing attack. NOTE: the Supplier's position is that the pwresettime configuration defaults to 30 minutes, the pwresettime configuration is a hard control enforced via flag PWRESET_STATUS_ALREADYSENT, and no further password-reset email messages are sent if this flag is active for a specific email address.
