CVE-2025-68675 Apache CVE debrief

Who should care

Airflow users and administrators should assess their exposure to this vulnerability and take steps to upgrade to fixed versions and review existing connections. This includes reviewing and updating existing connections to ensure proxy credentials are properly masked and monitoring logs for potential exposure of proxy credentials. Affected operator, platform, vulnerability-management, and security-team impact should be evaluated to ensure proper mitigation.

Why it matters

CVE-2025-68675 is a high-severity vulnerability in Apache Airflow that could lead to the exposure of proxy credentials in log output. Airflow users and administrators should assess their exposure and take steps to upgrade to fixed versions and review existing connections.

• Potential exposure of proxy credentials in log output
• Need to upgrade to fixed versions to prevent exposure
• Review and update existing connections to ensure proxy credentials are properly masked
• Monitoring logs for potential exposure of proxy credentials

Technical summary

In Apache Airflow versions before 3.1.6, and 2.11.1, 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.

Defensive priority

Airflow users should assess exposure and upgrade to fixed versions

Recommended defensive actions

• Upgrade to Apache Airflow 3.1.6 or later for Airflow 3, and 2.11.1 or later for Airflow 2
• Review and update existing connections to ensure proxy credentials are properly masked
• Monitor logs for potential exposure of proxy credentials
• Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up
• Review the supplied official advisory or CVE record to validate affected scope, severity, and vendor guidance
• Plan vendor-supported updates or mitigations through normal change control where exposure is confirmed
• Check relevant monitoring, detection, and logs for exposed assets that need extra review

Evidence notes

The CVE record and NVD entry provide details on the vulnerability in Apache Airflow versions before 3.1.6 and 2.11.1, where proxy credentials could be exposed in log output due to the proxies and proxy fields within a Connection not being treated as sensitive by default.
