Apache Airflow audit-log secrets masker redacts by key name only
Apache Airflow audit log stored Connection and Variable secret values in cleartext because the secrets masker matched only on configured sensitive key names.
Cleartext storage of secrets in Apache Airflow audit log
Apache Airflow stores Connection and Variable secret values in cleartext in the audit log's Log.extra column. An authenticated low-privilege user with read access to the event-log or audit API can read these rows without prior access to the affected connection or variable, recovering the credentials verbatim. This affects all users running vulnerable Apache Airflow versions.
What to do: Upgrade to Apache Airflow 3.4.0 or later. Apply Apache update for CVE-2026-50204.
| Product | Affected | Fixed in |
|---|---|---|
| Apache Airflow | < 3.4.0 | 3.4.0 |
Order-of-magnitude estimate by the model from install counts, market share and public scan data it knows; verify before quoting.
Apache Airflow's audit log stored Connection and Variable secret values in cleartext in the `Log.extra` column because the secrets masker matched only on configured sensitive key names. An authenticated low-privilege user with read access to the event-log / audit API — with no prior access to the affected connection or variable — could read those rows and recover the credentials verbatim. Users should upgrade to apache-airflow 3.4.0 or later, which masks these values and restricts the affected audit rows to authorized users. Airflow 2.x is also affected; Airflow 2 has reached end of life and will not receive a fix, so Airflow 2 users should upgrade to Apache Airflow 3.4.0 or later.
