   More details on the CVE: https://www.cvedetails.com/cve/CVE-2025-54831/
   
   > Apache Airflow 3 introduced a change to the handling of sensitive 
information in Connections. The intent was to restrict access to sensitive 
connection fields to Connection Editing Users, effectively applying a 
"write-only" model for sensitive values.
   
   > In Airflow 3.0.3, this model was unintentionally violated: sensitive 
connection information could be viewed by users with READ permissions through 
both the API and the UI. This behavior also bypassed the 
`AIRFLOW__CORE__HIDE_SENSITIVE_VAR_CONN_FIELDS` configuration option.
   
   > This issue does not affect Airflow 2.x, where exposing sensitive 
information to connection editors was the intended and documented behavior.
   
   
   Unmasking values in export in UI, explicitly brings back the condition that 
triggered the CVE in the first place.
