If you cannot patch yet, restrict access to authenticated users and monitor for unusual memory usage patterns. Avoid exposing the plugin resources endpoint to untrusted users.
Description
A request to the Grafana plugin resources endpoint can cause unbounded memory allocation by reading the entire request body into memory. An authenticated user can exploit this to trigger an out-of-memory condition, potentially causing a denial of service.
