CVE-2026-74044

Wazuh wazuh-manager

Wazuh 4.0.0 before 4.14.6 contains a path traversal vulnerability that allows authenticated cluster peers to delete arbitrary directory contents by supplying a traversal-shaped node name in the cluster hello payload without validation. Attackers holding a valid cluster Fernet key can craft a malicious node name and disconnect, triggering the master's peer cleanup routine to remove the contents of arbitrary directories within the Wazuh installation path writable by the wazuh user.
