CVE-2026-65017 is a medium-severity flaw (CVSS 6.5) affecting airflow. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

Apache Airflow's Config API did not mask team-scoped sensitive configuration values in multi-team deployments. When an administrator has enabled multi-team mode and exposed the Config API, an authenticated Viewer holding only configuration-read access — with no prior access to the secret — could read a team-scoped Celery broker URL, including its embedded credentials, in cleartext, while the equivalent global option was correctly masked.

Timeline

apache airflow UPGRADE
Affected: >= 3.3.0 and < 3.3.1
Fixed in: 3.3.1
Safe to downgrade to: a release before 3.3.0
1. Check installed version
apt-cache policy airflow || rpm -q airflow || airflow --version
2. UPGRADE to 3.3.1 (Debian / Ubuntu)
sudo apt update && sudo apt install --only-upgrade airflow
2. UPGRADE (RHEL / Amazon Linux / Fedora)
sudo dnf upgrade airflow
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 3.3.0 (Debian / Ubuntu)
apt-cache madison airflow sudo apt install airflow=<VERSION_BEFORE_3.3.0> sudo apt-mark hold airflow
3. If no update is available yet, DOWNGRADE (RHEL / Amazon Linux / Fedora)
dnf --showduplicates list airflow sudo dnf downgrade airflow-<VERSION_BEFORE_3.3.0> sudo dnf versionlock add airflow
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.
