CVE-2026-32760
CriticalSummary
File Browser to interfejs zarządzania plikami, który w wersjach 2.61.2 i poniżej pozwala na rejestrację pełnego konta administratora przez nieautoryzowanych użytkowników, gdy opcja samodzielnej rejestracji jest włączona. Handler rejestracji nie ma zabezpieczeń, które uniemożliwiają nadawanie uprawnień administratora nowym użytkownikom.
Risk Assessment
Organizacja narażona jest na ryzyko, że każdy nieautoryzowany użytkownik może uzyskać pełne uprawnienia administratora, co prowadzi do potencjalnej utraty kontroli nad plikami i ustawieniami serwera. Może to skutkować poważnymi naruszeniami bezpieczeństwa.
Recommendation
Zaleca się aktualizację do wersji 2.62.0, aby usunąć tę podatność. Należy również sprawdzić i dostosować ustawienia domyślne, aby zapobiec przypadkowemu nadaniu uprawnień administratora nowym użytkownikom.

- 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)
File Browser is a file managing interface for uploading, deleting, previewing, renaming, and editing files within a specified directory. In versions 2.61.2 and below, any unauthenticated visitor can register a full administrator account when self-registration (signup = true) is enabled and the default user permissions have perm.admin = true. The signup handler blindly applies all default settings (including Perm.Admin) to the new user without any server-side guard that strips admin from self-registered accounts. The signupHandler is supposed to create unprivileged accounts for new visitors. It contains no explicit user.Perm.Admin = false reset after applying defaults. If an administrator (intentionally or accidentally) configures defaults.perm.admin = true and also enables signup, every account created via the public registration endpoint is an administrator with full control over all files, users, and server settings. This issue has been resolved in version 2.62.0.
