Routine

MEDIUM 6.5UPGRADE

CVE-2026-66018 is a medium-severity flaw (CVSS 6.5) affecting artifactory. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

Build readers can access another repository's environment properties. A caller with read access to an ordinary repository can select a readable repository parameter while retrieving environment properties for a protected build, exposing build environment secrets (confidentiality impact; no integrity or availability impact demonstrated).

Why this priority

No elevated risk signals yet

A fixed release or distro patch exists.

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 7.146.0 (Debian / Ubuntu)

apt-cache madison artifactory sudo apt install artifactory=<VERSION_BEFORE_7.146.0> sudo apt-mark hold artifactory

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

dnf --showduplicates list artifactory sudo dnf downgrade artifactory-<VERSION_BEFORE_7.146.0> sudo dnf versionlock add artifactory

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.
