MEDIUM 6.5UPGRADE

CVE-2026-72681 is a medium-severity flaw (CVSS 6.5) affecting kibana. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

Kibana Agent Builder does not correctly verify that the requesting user holds the privileges required by a separate Kibana feature before it creates and runs a tool that invokes that feature's functionality. This allows privilege escalation and could lead to disclosure of sensitive information that the user is not authorized to read.

Why this priority

No elevated risk signals yet

elastic kibana UPGRADE

Affected: >= 9.4.0 and < 9.4.4

Fixed in: 9.4.4

Safe to downgrade to: a release before 9.4.0

1. Check installed version

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

2. UPGRADE to 9.4.4 (Debian / Ubuntu)

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

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade kibana

Note

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

3. If no update is available yet, DOWNGRADE to a release before 9.4.0 (Debian / Ubuntu)

apt-cache madison kibana sudo apt install kibana=<VERSION_BEFORE_9.4.0> sudo apt-mark hold kibana

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

dnf --showduplicates list kibana sudo dnf downgrade kibana-<VERSION_BEFORE_9.4.0> sudo dnf versionlock add kibana

Downgrade risk

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

After downgrade

Restart the service, and keep the package held until a fixed release ships.
