CVE-2026-4370
CriticalSummary
Zidentyfikowano podatność w Juju od wersji 3.2.0 do 3.6.19 oraz od wersji 4.0 do 4.0.4, gdzie wewnętrzny klaster bazy danych Dqlite nie przeprowadza właściwej autoryzacji TLS dla klientów i serwerów. Punkt końcowy bazy danych kontrolera Juju nie weryfikuje certyfikatów klientów, co pozwala nieautoryzowanemu atakującemu dołączyć do klastra bazy danych.
Risk Assessment
Atakujący z dostępem do sieci kontrolera Juju może wykorzystać tę lukę, uzyskując pełny dostęp do bazy danych, co prowadzi do całkowitego kompromitacji danych.
Recommendation
Zaleca się aktualizację Juju do najnowszej wersji, która naprawia tę podatność oraz wdrożenie dodatkowych środków zabezpieczających, aby ograniczyć dostęp do portu Dqlite.

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.

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)
A vulnerability was identified in Juju from version 3.2.0 until 3.6.19 and from version 4.0 until 4.0.4, where the internal Dqlite database cluster fails to perform proper TLS client and server authentication. Specifically, the Juju controller's database endpoint does not validate client certificates when a new node attempts to join the cluster. An unauthenticated attacker with network reachability to the Juju controller's Dqlite port can exploit this flaw to join the database cluster. Once joined, the attacker gains full read and write access to the underlying database, allowing for total data compromise.
