CVE-2026-113504
Apache Airflow: Secrets masker: pattern-based masking bounded at depth 5 returns deeply-nested registered secrets in cleartext
Description
Apache Airflow's secrets masker stopped descending into nested structures after five levels, so a secret registered with the masker — for example a Connection password or a Variable value — that appeared more than five containers deep under non-sensitive keys was shown in cleartext in task logs and rendered template fields. A user who can read task logs or rendered templates, but is not meant to see those secrets, could read them. Users are advised to upgrade to apache-airflow 3.4.0 or later.
