CVE-2026-5059
CriticalSummary
Podatność CVE-2026-5059 dotyczy serwera aws-mcp, umożliwiając zdalnym atakującym wykonanie dowolnego kodu na zainfekowanych instalacjach. Problem wynika z braku odpowiedniej walidacji ciągu dostarczonego przez użytkownika przed jego użyciem do wykonania wywołania systemowego.
Risk Assessment
Wykorzystanie tej podatności może prowadzić do przejęcia kontroli nad serwerem MCP, co stwarza poważne zagrożenie dla bezpieczeństwa organizacji. Atakujący mogą wykonywać dowolne polecenia w kontekście serwera, co może prowadzić do utraty danych lub kompromitacji systemu.
Recommendation
Zaleca się natychmiastowe zaktualizowanie oprogramowania aws-mcp-server do najnowszej wersji, która zawiera poprawki bezpieczeństwa. Dodatkowo, warto wdrożyć mechanizmy monitorowania i ograniczenia dostępu do serwera, aby zminimalizować ryzyko wykorzystania 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)
aws-mcp-server AWS CLI Command Injection Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of aws-mcp-server. Authentication is not required to exploit this vulnerability. The specific flaw exists within the handling of the allowed commands list. The issue results from the lack of proper validation of a user-supplied string before using it to execute a system call. An attacker can leverage this vulnerability to execute code in the context of the MCP server. Was ZDI-CAN-27969.
