CVE-2026-112339Wazuh 3.9.0 before 4.14.9 Missing TLS Hostname Verification in fluent-forward Module

Descripción

Wazuh from 3.9.0 before 4.14.9 contains a missing TLS hostname verification vulnerability in the fluent-forward module's wm_fluent_ssl_ctx() that allows network attackers to impersonate the Fluentd collector by presenting any certificate chaining to the configured ca_file. Attackers who redirect the connection via DNS, ARP, or on-path positions can receive forwarded security telemetry and the shared_key_hexdigest for offline cracking.
