Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
In Airflow versions prior to 1.10.13, when creating a user using airflow CLI, the password gets logged in plain text in the Log table in Airflow Metadatase. Same happened when creating a Connection with a password field.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · high confidence

In Apache Airflow versions prior to 1.10.13, sensitive credentials (user passwords and connection passwords) are logged in plain text to the Airflow Metadata database's Log table when created via the CLI or when configuring Connections. This exposes authentication credentials in logs accessible within the metadata database.

MitigationUpgrade to Airflow 1.10.13 or later which prevents password fields from being logged. Additionally, audit the Log table for any exposed credentials and rotate affected passwords/credentials as a precautionary measure.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Check installed Airflow version
    Run 'airflow version' or query the airflow_version table in the metadata database
    Affected if The version is lower than 1.10.13 (e.g., 1.10.12, 1.10.11, etc.)
  2. Examine Log table for plain text passwords
    Connect to the Airflow metadata database and query the Log table for patterns matching passwords or sensitive credential strings. Look for entries containing keywords like 'password', 'pwd', or connection strings with embedded secrets.
    Affected if Any Log records contain plain text passwords or connection passwords in the log_message or other text fields
  3. Identify connections created via CLI
    Query the connection table in the metadata database and cross-reference with the Log table using timestamps to identify if connections were created or modified around the time of Log entries containing sensitive data
    Affected if Connection records exist in the database and corresponding Log entries contain plain text credential data
  4. Check for user password logs
    Query the Log table for entries related to user creation or password reset operations, particularly those initiated via CLI using commands like 'airflow users create'
    Affected if Log entries exist for user management operations performed via CLI containing visible password data

You are affected if your Airflow version is prior to 1.10.13 AND the Log table in your metadata database contains any plain text passwords or connection credentials.

Upgrade available Upgrade to 1.10.13 or later
Fixed in 1.10.13
Interim mitigation

Upgrade to Airflow 1.10.13 or later which prevents password fields from being logged. Additionally, audit the Log table for any exposed credentials and rotate affected passwords/credentials as a precautionary measure.
