CVE-2026-48828: CWE-200: Exposure of Sensitive Information to an Unauthorized Actor in Apache Software Foundation Apache Airflow
CVE-2026-48828 is a vulnerability in Apache Airflow's Bulk Variables API where sensitive JSON-typed variables with secret-suffixed keys (e.g., *_password, *_token, *_secret) are not properly redacted. Authenticated users with bulk Variable read permission can access plaintext values that should be hidden. The issue affects Apache Airflow versions prior to 3.3.0. The vulnerability is fixed in version 3.3.0 and later.
AI Analysis
Technical Summary
The Bulk Variables API in Apache Airflow fails to pass the variable's key to the redactor function, bypassing the key-based redaction check that hides sensitive values for keys ending with secret-related suffixes. This allows authenticated users with bulk Variable read permission to retrieve plaintext sensitive data from JSON variables that would normally be redacted. The vulnerability affects deployments storing sensitive values in JSON-typed Airflow Variables under secret-suffixed key names. The fix was introduced in Apache Airflow 3.3.0; no backport is available for the 3.2.x branch.
Potential Impact
An authenticated user with bulk Variable read permission can access sensitive information in plaintext that should be redacted, potentially exposing secrets such as passwords, tokens, or keys stored in JSON variables. This exposure could lead to unauthorized access or misuse of sensitive credentials within affected Airflow deployments.
Mitigation Recommendations
Upgrade Apache Airflow to version 3.3.0 or later, where the issue is fixed. There is no backport for 3.2.x versions. Until upgrading, restrict bulk Variable read permissions to trusted users only to minimize exposure risk.
