The JSON datasource plugin ( https://grafana.com/grafana/plugins/marcusolsson-json-datasource/ ) is a Grafana Labs maintained plugin for Grafana that allows for retrieving and processing JSON data from a remote endpoint (including a specific sub-path) configured by an administrator. Due to inadequate sanitization of the dashboard-supplied path parameter, it was possible to include path traversal characters (../) in the path parameter and send requests to paths on the configured endpoint outside the configured sub-path. This means that if the datasource was configured by an administrator to point at some sub-path of a domain (e.g. https://example.com/api/some_safe_api/ ), it was possible for an editor to create a dashboard referencing the datasource which issues queries containing path traversal characters, which would in turn cause the datasource to instead query arbitrary subpaths on the configured domain (e.g. https://example
