CVE-2026-33640
CriticalSummary
Outline to usługa umożliwiająca współpracę nad dokumentacją. W wersjach od 0.86.0 do 1.6.0, Outline nie unieważnia kodów OTP na podstawie liczby lub częstotliwości nieprawidłowych prób, co pozwala na obejście ograniczeń i umożliwia ataki brute force na konta użytkowników.
Risk Assessment
Atakujący mogą przeprowadzać nieograniczone próby wprowadzenia kodów OTP, co prowadzi do przejęcia kont użytkowników. To stwarza poważne zagrożenie dla bezpieczeństwa danych organizacji.
Recommendation
Zaleca się aktualizację do wersji 1.6.0 lub nowszej, aby naprawić tę podatność i zabezpieczyć system przed atakami brute force.

- CVE-2026-7826Critical
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)
Outline is a service that allows for collaborative documentation. Outline implements an Email OTP login flow for users not associated with an Identity Provider. Starting in version 0.86.0 and prior to version 1.6.0, Outline does not invalidate OTP codes based on amount or frequency of invalid submissions, rather it relies on the rate limiter to restrict attempts. Consequently, identified bypasses in the rate limiter permit unrestricted OTP code submissions within the codes lifetime. This allows attackers to perform brute force attacks which enable account takeover. Version 1.6.0 fixes the issue.
