Short explanation
Apache Airflow contains a vulnerability where the secrets masking mechanism stops descending into nested structures after five levels, resulting in sensitive data being exposed in cleartext (S0).
Users who can read task logs or rendered templates, but are not meant to see those secrets, could read them in cleartext (S0).
What should be done?
- Upgrade apache-airflow to version 3.4.0 or later (S0)
Chain of evidence and sources
Apache Airflow sır maskeleme mekanizması beş seviyeden derin yapıları tarayamamaktadır (S0).
Kullanıcıların apache-airflow 3.4.0 veya sonraki sürüme yükseltmesi önerilmektedir (S0).
Show the technical text from the sources
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.
