MEDIUMCVSS v3.1 5.0Vulnerability

CVE-2026-64686

OpenSearch Dashboards is an open-source data visualization tool designed to work with OpenSearch. From versions 2.14.0 to before 2.19.6, and 3.0.0 to before 3.7.0, a Server-Side Request Forgery (SSRF) vulnerability in OpenSearch Dashboards exists in the fetchDataSourceMetaData route. The sibling test_connection route validates incoming endpoint URLs via isValidURL() against configured endpointDeniedIPs and endpointAllowlistedSuffixes lists, but fetchDataSourceMetaData accepts the same input shape without performing this validation. An authenticated user can supply an internal or loopback endpoint to probe internal network resources. This issue has been patched in versions 2.19.6 and 3.7.0.
