Detailsinfo

A vulnerability, which was classified as problematic, has been found in Apache Airflow up to 2.11.0. This issue affects an unknown code. The manipulation with an unknown input leads to a log file vulnerability. Using CWE to declare the problem leads to CWE-532. Information written to log files can be of a sensitive nature and give valuable guidance to an attacker or expose sensitive user information. Impacted is confidentiality. The summary by CVE is:

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
