CVE-2026-25769
CriticalSummary
Wazuh to darmowa i otwarta platforma służąca do zapobiegania, wykrywania i reagowania na zagrożenia. W wersjach od 4.0.0 do 4.14.2 występuje podatność na zdalne wykonanie kodu (RCE) spowodowana deserializacją niezaufanych danych, co wpływa na wszystkie wdrożenia Wazuh w trybie klastrowym.
Risk Assessment
Organizacje z kompromitowanym węzłem roboczym mogą być narażone na pełne zdalne wykonanie kodu na węźle głównym z uprawnieniami roota, co stwarza poważne zagrożenie dla bezpieczeństwa systemu.
Recommendation
Zaleca się aktualizację do wersji 4.14.3, która naprawia tę podatność, aby zabezpieczyć system przed potencjalnymi atakami.

A path traversal vulnerability was found in gvproxy, the network forwarder provided by the gvisor-tap-vsock package. The unauthenticated /services/forwarder/expose endpoint does not validate the caller-supplied socket path, allowing an attacker to delete arbitrary files on the host system.
- CVE-2026-107909Critical
A heap-based out-of-bounds write in the ws_read_frame function (src/bolt/ws.c) and the buffer_apply_mask function (src/bolt/buffer.c) in FalkorDB before 4.20.0 allows a remote unauthenticated attacker to cause a denial of service and possibly corrupt heap memory by sending a WebSocket frame with a 64-bit extended payload length to the Bolt port. The payload length is not bounded, and the only bounds check in buffer_apply_mask is an ASSERT(), which is compiled out in release builds, so the function XORs memory beyond the end of the receive buffer with the attacker-supplied mask key. Only deployments that enable the Bolt endpoint (BOLT_PORT, disabled by default) are affected.
- CVE-2026-107908Critical
A heap-based out-of-bounds write in the BoltReadHandler function (src/bolt/bolt_api.c) in FalkorDB before 4.20.0 allows a remote unauthenticated attacker to cause a denial of service and possibly execute arbitrary code by sending a Bolt RESET message with an attacker-chosen chunk size to the Bolt port. The handler checks the size only with ASSERT(), which is compiled out in release builds, then computes a destination pointer from the wire-supplied 16-bit size and moves buffered data up to about 64 KiB backwards past the start of the read buffer. Only deployments that enable the Bolt endpoint (BOLT_PORT, disabled by default) are affected.
Original NVD description (English source)
Wazuh is a free and open source platform used for threat prevention, detection, and response. Versions 4.0.0 through 4.14.2 have a Remote Code Execution (RCE) vulnerability due to Deserialization of Untrusted Data). All Wazuh deployments using cluster mode (master/worker architecture) and any organization with a compromised worker node (e.g., through initial access, insider threat, or supply chain attack) are impacted. An attacker who gains access to a worker node (through any means) can achieve full RCE on the master node with root privileges. Version 4.14.3 fixes the issue.
