CVE-2026-25219
CWE-200Published: April 15, 2026· Updated: Apr 17, 2026
Official Description
The `access_key` and `connection_string` connection properties were not marked as sensitive names in secrets masker. This means that user with read permission could see the values in Connection UI, as well as when Connection was accidentaly logged to logs, those values could be seen in the logs. Azure Service Bus used those properties to store sensitive values. Possibly other providers could be also affected if they used the same fields to store sensitive data.
If you used Azure Service Bus connection with those values set or if you have other connections with those values storing sensitve values, you should upgrade Airflow to 3.1.8
Technical Analysis
CVE-2026-25219 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.

A successful exploit results in complete confidentiality breach (data exposure), with a CVSS base score of 6.5.
From a weakness classification perspective (CWE-200): Information exposure vulnerabilities leak sensitive data to unauthorized actors.
