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.
Default status is the baseline for the product, each version can override it (e.g. patched versions marked unaffected).
