Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
DAG Author (who already has quite a lot of permissions) could manipulate database of Airflow 2 in the way to execute arbitrary code in the web-server context, which they should normally not be able to do, leading to potentially remote code execution in the context of web-server (server-side) as a result of a user viewing historical task information. The functionality responsible for that (log template history) has been disabled by default in 2.11.1 and users should upgrade to Airflow 3 if they want to continue to use log template history. They can also manually modify historical log file names if they want to see historical logs that were generated before the last log template change.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis
How this class of weakness works · CWE-94

The application evaluates attacker-influenced input as code, handing them a way to run logic inside the process. Depending on the runtime this can escalate directly to remote code execution. Remediation means removing dynamic evaluation of untrusted input and replacing it with safe, data-driven alternatives.

Recommended fix High confidence

Airflow 2.11.1 or later (or Airflow 3.x for continued log template history functionality)

  1. 1. Plan for an upgrade during a maintenance window to minimize disruption.
  2. 2. Review the Airflow 2.11.1 release notes and migration guide for any configuration changes: https://airflow.apache.org/docs/apache-airflow/2.11.1/
  3. 3. Take a backup of the Airflow metadata database before upgrading.
  4. 4. Stop the Airflow webserver, scheduler, and worker services.
  5. 5. Upgrade Airflow using your package manager (e.g., `pip install apache-airflow==2.11.1` or `pip install --upgrade apache-airflow>=2.11.1`).
  6. 6. Run database migrations: `airflow db upgrade`.
  7. 7. Restart all Airflow services (webserver, scheduler, workers).
  8. 8. Verify the webserver is running and the UI is accessible.
Caveat Log template history is disabled by default in 2.11.1; upgrading to Airflow 3.x (if chosen) has its own major-version breaking changes
