CVE-2025-3717Network attack vector

Cross-user data disclosure via OAuth identity mix-up

Published Nov 11, 2025 · Updated Nov 11, 2025

Information disclosure in Grafana Snowflake Datasource Plugin 1.5.0 through 1.14.0 allows remote authenticated users to view unauthorized data. The OAuth passthrough handler uses the wrong viewer identifier for a query and returns information authorized for another user. Exposure requires OAuth passthrough to be enabled and multiple users to access the same datasource concurrently on one Grafana instance.
