{"id":"CVE-2026-113504","published":"2026-11-09T10:17:05.303","lastModified":"2026-11-10T21:12:58.107","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. 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.","cvssScore":null,"cvssSeverity":null,"cvssVector":null,"cwes":["CWE-497"],"vendors":[],"products":[],"references":[{"url":"https://github.com/apache/airflow/pull/73793","tags":[]},{"url":"https://lists.apache.org/thread.html/c0bzrpq913qh7srwdmx0smvt1tgvthrr","tags":[]},{"url":"http://www.openwall.com/lists/oss-security/2026/11/09/19","tags":[]}],"exploitRefs":[{"url":"https://github.com/apache/airflow/pull/73793","tags":[]}],"hasPoc":true,"ai":null}
