HIGH 7.1UPGRADE

CVE-2026-74038 is a high-severity flaw (CVSS 7.1) 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 unauthenticated remote attackers to cause denial of service by enrolling an agent with a dot-sequence name such as ".." through the enrollment port. Attackers exploit insufficient validation in OS_IsValidName() and unsafe path concatenation in delete_diff() to resolve the traversal to the parent queue directory, causing its subdirectories to be removed and stopping all

wazuh wazuh UPGRADE

Affected: >= 4.0.0 and < 4.14.6

Fixed in: 4.14.6

Safe to downgrade to: a release before 4.0.0

1. Check installed version

apt-cache policy wazuh || rpm -q wazuh || wazuh --version

2. UPGRADE to 4.14.6 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade wazuh

Note

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

apt-cache madison wazuh sudo apt install wazuh=<VERSION_BEFORE_4.0.0> sudo apt-mark hold wazuh

3. If no update is available yet, DOWNGRADE (RHEL / Amazon Linux / Fedora)

dnf --showduplicates list wazuh sudo dnf downgrade wazuh-<VERSION_BEFORE_4.0.0> sudo dnf versionlock add wazuh

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