CVE-2026-33875
CriticalSummary
Gematik Authenticator zapewnia bezpieczną autoryzację użytkowników do logowania się do aplikacji zdrowotnych. Wersje przed 4.16.0 są podatne na przejęcie procesu autoryzacji, co może pozwolić atakującym na uwierzytelnienie się jako ofiary, które kliknęły złośliwy link.
Risk Assessment
Organizacje mogą być narażone na nieautoryzowany dostęp do kont użytkowników, co może prowadzić do wycieku danych osobowych i naruszenia prywatności.
Recommendation
Zaleca się aktualizację Gematik Authenticator do wersji 4.16.0 lub nowszej, aby zastosować poprawkę. Nie ma znanych obejść tej podatności.

- 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)
Gematik Authenticator securely authenticates users for login to digital health applications. Versions prior to 4.16.0 are vulnerable to authentication flow hijacking, potentially allowing attackers to authenticate with the identities of victim users who click on a malicious deep link. Update Gematik Authenticator to version 4.16.0 or greater to receive a patch. There are no known workarounds.
