CVE-2025-27555: Apache Airflow: Connection Secrets not masked in UI when Connection are added via Airflow cli

[Jarek Potiuk <potiuk () apache org>]

Severity: low 

Affected versions:

- Apache Airflow (apache-airflow) before 2.11.1

Description:

Airflow versions before 2.11.1 have a vulnerability that allows authenticated users with audit log access to see 
sensitive values in audit logs which they should not see. When sensitive connection parameters were set via airflow 
CLI, values of those variables appeared in the audit log and were stored unencrypted in the Airflow database. While 
this risk is limited to users with audit log access, it is recommended to upgrade to Airflow 2.11.1 or a later version, 
which addresses this issue. Users who previously used the CLI to set connections should manually delete entries with 
those connection sensitive values from the log table. This is similar but not the same issue as CVE-2024-50378
