Secret disclosure via unmasked pending-task templates
Published Nov 14, 2022 · Updated Apr 30, 2025
Sensitive-information exposure in Apache Airflow before 2.3.1 allows attackers to view unmasked secrets in the Rendered Templates UI. When the webserver renders fields for a task that has not started, the pending-task path leaves referenced Variable values unredacted instead of passing them through secret masking. Access to the affected task's Rendered Templates view and a DAG whose pending task references a secret are required; the demonstrated consequence is read-only disclosure.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
