A user who is permitted to trigger that Dag - a lower-trust role than the Dag author, and one that needs no Teradata credentials of its own - could therefore supply SQL fragments that execute under the connection the task runs as, and could additionally redirect the task at any other connection defined in the deployment, because the connection id was itself a free-text Param. Only deployments that run this example Dag, or a Dag copied from it, are affected; the provider's operator code is unchanged. Users of apache-airflow-providers-teradata are recommended to upgrade to version 3.7.0 or later, whose example constrains the Params to validated identifiers and a closed value set and removes connection selection and free-form option strings from trigger-time input. Upgrading does not change a Dag already copied from the example; users who copied it should apply the same constraints to their copy.","state":0,"publishedAt":"2026-09-29T10:00:34.961+00:00","modifiedAt":"2026-09-29T18:28:37.38+00:00","affected":[{"ecosystem":"https://pypi.python.org","name":"apache-airflow-providers-teradata","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"defaultStatus\": \"unaffected\",\n                    \"packageURL\": \"pkg:pypi/apache-airflow-providers-teradata\",\n                    \"product\": \"Apache Airflow Teradata provider\",\n                    \"vendor\": \"Apache Software Foundation\",\n                    \"versions\": [\n                        {\n                            \"lessThan\": \"3.7.0\",\n                            \"status\": \"affected\",\n                            \"version\": \"0\",\n                            \"versionType\": \"semver\"\n                        }\n                    ],\n                    \"collectionURL\": \"https://pypi.python.org\",\n                    \"packageName\": \"apache-airflow-providers-teradata\"\n                }"}],"metrics":[],"references":["https://github.com/apache/airflow/pull/72714","https://lists.apache.org/thread/js9pmhj1j6552gpn1j8wdz579pb46t0d"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-86843","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-86843","identifiers":["CVE-2026-86843"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
