CVE-2026-33409
CriticalSummary
Parse Server, otwarte oprogramowanie backendowe, ma lukę umożliwiającą obejście uwierzytelniania przed wersjami 8.6.52 i 9.6.0-alpha.41. Atakujący może zalogować się jako dowolny użytkownik, który powiązał swoje konto z zewnętrznym dostawcą uwierzytelniania, znając jedynie identyfikator dostawcy.
Risk Assessment
Luka ta pozwala atakującemu na uzyskanie pełnego dostępu do konta użytkownika, co może prowadzić do poważnych naruszeń danych. Organizacje korzystające z podatnych wersji Parse Server są narażone na nieautoryzowany dostęp do wrażliwych informacji.
Recommendation
Zaleca się aktualizację do wersji 8.6.52 lub 9.6.0-alpha.41, aby usunąć tę lukę. Dodatkowo, warto rozważyć ustawienie opcji allowExpiredAuthDataToken na false, aby zwiększyć bezpieczeństwo.

- 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)
Parse Server is an open source backend that can be deployed to any infrastructure that can run Node.js. Prior to versions 8.6.52 and 9.6.0-alpha.41, an authentication bypass vulnerability allows an attacker to log in as any user who has linked a third-party authentication provider, without knowing the user's credentials. The attacker only needs to know the user's provider ID to gain full access to their account, including a valid session token. This affects Parse Server deployments where the server option allowExpiredAuthDataToken is set to true. The default value is false. This issue has been patched in versions 8.6.52 and 9.6.0-alpha.41.
