CVE-2025-68675: Apache Airflow: proxy credentials for various providers might leak in task logs

[Ephraim Anierobi <ephraimanierobi () apache org>]

Severity: low 

Affected versions:

- Apache Airflow (apache-airflow) before 3.1.6

Description:

In Apache Airflow versions before 3.1.6, the proxies and proxy fields within a Connection may include proxy URLs 
containing embedded authentication information. These fields were not treated as sensitive by default and therefore 
were not automatically masked in log output. As a result, when such connections are rendered or printed to logs, proxy 
credentials embedded in these fields could be exposed.

Users are recommended to upgrade to 3.1.6 or later, which fixes this issue
