CVE-2026-40050
CriticalSummary
CrowdStrike wydał aktualizacje zabezpieczeń w celu usunięcia krytycznej podatności na nieautoryzowany dostęp do systemu plików (CVE-2026-40050) w LogScale. Podatność ta dotyczy tylko klientów hostujących określone wersje LogScale i nie wpływa na klientów Next-Gen SIEM.
Risk Assessment
Podatność umożliwia zdalnemu atakującemu odczyt dowolnych plików z systemu plików serwera bez autoryzacji, co stanowi poważne zagrożenie dla bezpieczeństwa danych organizacji.
Recommendation
Klienci korzystający z LogScale w wersji self-hosted powinni niezwłocznie zaktualizować oprogramowanie do wersji zawierającej poprawki, aby usunąć tę podatność.

- 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)
CrowdStrike has released security updates to address a critical unauthenticated path traversal vulnerability (CVE-2026-40050) in LogScale. This vulnerability only requires mitigation by customers that host specific versions of LogScale and does not affect Next-Gen SIEM customers. The vulnerability exists in a specific cluster API endpoint that, if exposed, allows a remote attacker to read arbitrary files from the server filesystem without authentication. Next-Gen SIEM customers are not affected and do not need to take any action. CrowdStrike mitigated the vulnerability for LogScale SaaS customers by deploying network-layer blocks to all clusters on April 7, 2026. We have proactively reviewed all log data and there is no evidence of exploitation. LogScale Self-hosted customers should upgrade to a patched version immediately to remediate the vulnerability. CrowdStrike identified this vulnerability during continuous and ongoing product testing.
