Apache Airflow · Apache Airflow Teradata Provider · CVE-2026-86843
**Name of the Vulnerable Software and Affected Versions**
apache-airflow-providers-teradata versions prior to 3.7.0
**Description**
The compute-cluster example Dag in the Apache Airflow Teradata provider declares Dag Params as unconstrained free text. These values are templated directly into compute-cluster operators, which interpolate them into Teradata DDL (Data Definition Language). A user with permissions to trigger the Dag can provide SQL fragments that execute using the task's connection. Additionally, because the connection ID is a free-text Param, the user can redirect the task to any other connection defined in the deployment.
**Recommendations**
Upgrade to version 3.7.0 or later.
For users who copied the example Dag, apply constraints to the Params to use validated identifiers and a closed value set, and remove connection selection and free-form option strings from trigger-time input.
