CVE-2026-50204

Full vulnerability record from the local CVENow database.

Description

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.
