CVE-2026-31987
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 · uneditedJWT Tokens used by tasks were exposed in logs. This could allow UI users to act as Dag Authors. Users are advised to upgrade to Airflow version that contains fix. Users are recommended to upgrade to version 3.2.0, which fixes this issue.
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 analysisSensitive values — secrets, tokens, session identifiers, personal data — are written into log files, so anyone with access to the logs, which is often a broad group, obtains them. It turns a routine diagnostic into a credential leak. The fix is redacting sensitive data before it is logged and tightly restricting who can read the logs.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scoped3.2.0
Airflow 3.2.0
- 1. Backup your current Airflow configuration, metadata database, and DAG files
- 2. Stop the Airflow services (webserver, scheduler, worker)
- 3. Upgrade Airflow by installing version 3.2.0 using your package manager (e.g., pip install apache-airflow==3.2.0 or equivalent)
- 4. Run any required database migrations (airflow db migrate or airflow upgrade-db)
- 5. Verify the upgrade by checking that Airflow services start successfully
- 6. Confirm that JWT tokens are no longer exposed in logs by reviewing recent task logs
