# CVE-2026-30912: Apache Airflow: Exposing stack trace in case of constraint error

Status: published. Published: 2026-04-18. Updated: 2026-11-03.

In case of SQL errors, exception/stack trace of errors was exposed in API even if "api/expose_stack_traces" was set to false. That could lead to exposing additional information to potential attacker. Users are recommended to upgrade to Apache Airflow 3.2.0, which fixes the issue.
