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 in the top 21% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.

Deeper analysis AI-assisted summary

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

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.

Mitigating Controls

Likely Mitigating Controls AI

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.

addresses: CWE-532

Procedures mandate excluding sensitive data from logs to prevent unauthorized exposure via audit records.

addresses: CWE-532

Identifies insertion of sensitive data into logs, allowing detection of unauthorized disclosure.

addresses: CWE-532

Cross-organizational coordination enables agreement on what data to include in audit logs, directly reducing insertion of sensitive information.

addresses: CWE-532

Identifying logging as a data action allows prevention of sensitive information being inserted into log files.

addresses: CWE-532

The process of identifying and eradicating spilled information applies directly to sensitive data inserted into log files.

addresses: CWE-532

Specific processing rules for sensitive PII categories commonly include restrictions on logging, making insertion of such data into log files less likely.

addresses: CWE-532

PIAs detect planned or existing logging of PII and require removal or protection, preventing insertion of sensitive information into logs.

addresses: CWE-532

Limits insertion of sensitive operational details into logs by treating such data as key information requiring protection.

PR.PS-06 mostly match
prevents

Secure SDLC practices directly prohibit writing sensitive data to logs; eliminating the weakness satisfies only one narrow slice of the control.

PR.PS-04 partial match
prevents

Log generation configuration can and should exclude sensitive data, but the control statement focuses on availability rather than content filtering.

A.8.15 Logging mostly match
prevents

Requiring de-identification and privacy controls before logs leave the organization reduces the chance that sensitive data inadvertently captured in logs becomes exposed to external parties.

mitigates

By defining what records must be kept, where, and for how long, the control discourages the inadvertent inclusion of sensitive information in logs or other externally accessible files that fall outside the formal record system.

mitigates

Mandating deletion of temporary files and logs that may contain sensitive information prevents those artifacts from remaining accessible after the data is no longer needed.

A.8.11 Data masking partial match
mitigates

When log entries are produced from masked data sets, the control prevents the inadvertent insertion of sensitive values into externally accessible log files.

mitigates

DLP inspection of logs and file transfers can detect and block the inadvertent placement of sensitive tokens or credentials into externally accessible log files before they are written or transmitted.

prevents

Requiring restrictions on free-text fields and proper error-message handling stops developers from embedding or leaking sensitive data into logs or diagnostic output.
