CVE-2026-50204 is an information exposure vulnerability in Apache Airflow in which sensitive values submitted through bulk API endpoints were written to audit logs without masking. Specifically, Variable values and Connection extra contents could be logged in cleartext during bulk operations. As a result, authenticated users who can read audit logs may recover secrets even when they do not have direct permission to read the underlying Variables or Connections. The issue is caused by improper handling of sensitive data in logging paths for bulk endpoint submissions.
