CVE-2026-74044 is a medium-severity flaw (CVSS 6.5) affecting wazuh. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

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 installatio

wazuh wazuh UPGRADE

Affected: >= 4.0.0 and < 4.14.6

Fixed in: 4.14.6

Distros often backport fixes without changing the version number. Confirm with the distro advisory or changelog.

Downgrading can break dependent software and may reopen older bugs. Read the distro advisory first and test on a non-production host.
