CVE-2026-41084 is a high-severity flaw (CVSS 7.5) affecting airflow. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

A bug in Apache Airflow's bulk Task Instances API (`PATCH/DELETE /api/v2/dags/{dag_id}/dagRuns/{dag_run_id}/taskInstances`) evaluated authorization against the `dag_id` resolved from the URL path while operating on the `dag_id` / `dag_run_id` extracted from request-body entity fields. An authenticated UI/API user with edit permission on one Dag could mutate Task Instance state in any other Dag by keeping the authorized Dag's ID in the URL path an

apache airflow UPGRADE

Affected: >= 3.2.0 and < 3.2.2

Fixed in: 3.2.2

Safe to downgrade to: a release before 3.2.0

1. Check installed version

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

2. UPGRADE to 3.2.2 (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 3.2.0 (Debian / Ubuntu)

apt-cache madison airflow sudo apt install airflow=<VERSION_BEFORE_3.2.0> 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_3.2.0> 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.
