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

[Rahul Vats <rahulvats () apache org>]

Severity: low 

Affected versions:

- Apache Airflow (apache-airflow) before 3.2.0

Description:

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.
