Recommendation: Monitor — no exploitation signal at the moment.
The Loki datasource plugin's callResource handler contains a path traversal vulnerability. An authenticated Viewer-role user can escape the plugin's resource sandbox and access administrative Loki endpoints (e.g. /config, /services, /ready) to extract sensitive backend configuration and internal service information.
