CVE-2025-68675
Published: 16 January 2026
Summary
CVE-2025-68675 is a high-severity Insertion of Sensitive Information into Log File (CWE-532) vulnerability in Apache Airflow. Its CVSS base score is 7.5 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Unsecured Credentials (T1552); ranked at the 14.1th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified are NIST 800-53 AU-9 (Protection of Audit Information) and SI-2 (Flaw Remediation).
Deeper analysis
CVE-2025-68675 is an information disclosure vulnerability in Apache Airflow versions before 3.1.6 and 2.11.1. The issue stems from the proxies and proxy fields within a Connection, which can include proxy URLs containing embedded authentication information. These fields were not treated as sensitive by default, so they were not automatically masked in log output. As a result, proxy credentials could be exposed when such connections are rendered or printed to logs.
The vulnerability enables exploitation by any attacker who can access Airflow logs, such as through system access, log aggregation services, or misconfigured log storage. No special privileges, user interaction, or complex conditions are required, allowing remote attackers to obtain sensitive proxy credentials if a vulnerable Connection is configured with embedded authentication and logged.
Apache Airflow advisories recommend upgrading to version 3.1.6 or later for Airflow 3, and 2.11.1 or later for Airflow 2, which addresses the issue by properly masking these fields. Further details are provided in the GitHub pull request at https://github.com/apache/airflow/pull/59688, the Apache mailing list thread at https://lists.apache.org/thread/x6kply4nqd4vc4wgxtm6g9r2tt63s8c5, and the OSS-Security announcement at http://www.openwall.com/lists/oss-security/2026/01/15/6.

Remediating the software flaw by upgrading Apache Airflow to a patched version directly fixes the failure to mask sensitive proxy credentials in log outputs.
Protecting audit information from unauthorized access prevents exploitation by blocking attackers from reading logs containing exposed proxy credentials.
Filtering sensitive information from system outputs like logs mitigates disclosure of embedded proxy authentication details when connections are rendered or logged.
