Summary

The Apache Airflow connections API did not mask the apprise provider's `config` connection extra, which can embed notification-service credentials. A user with permission to read connections could retrieve it in cleartext, although Airflow 3 treats connection credentials as write-only.

Users are advised to upgrade to apache-airflow 3.4.0 or later. Airflow 2.x is also affected; Airflow 2 has reached end of life and will not receive a fix, so Airflow 2 users should upgrade to Apache Airflow 3.4.0 or later.

Patch / fix

  • Apache Software Foundation Apache Airflow 3.0.0, 3.4.0

Inferred packages

No advisory lists a package for this vulnerability yet. The CVE names these as products and links their GitHub repository, and the package registry names the same repository, so they are probably the affected packages. Low confidence: the versions are the CVE’s own for the product, and a stack check reports the package as unchecked when there are none.
