CRITICAL 9.1REMOTEWATCHLISTUPGRADE

CVE-2025-57735 is a critical-severity flaw (CVSS 9.1) affecting airflow. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

When user logged out, the JWT token the user had authtenticated with was not invalidated, which could lead to reuse of that token in case it was intercepted. In Airflow 3.2 we implemented the mechanism that implements token invalidation at logout. Users who are concerned about the logout scenario and possibility of intercepting the tokens, should upgrade to Airflow 3.2+ Users are recommended to upgrade to version 3.2.0, which fixes this issue.

apache airflow UPGRADE

Affected: >= 3.0.0 and < 3.2.0

Fixed in: 3.2.0

Safe to downgrade to: a release before 3.0.0

1. Check installed version

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

2. UPGRADE to 3.2.0 (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 3.0.0 (Debian / Ubuntu)

apt-cache madison airflow sudo apt install airflow=<VERSION_BEFORE_3.0.0> 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_3.0.0> 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.
