+## Reporting a Vulnerability
+
+If you find a vulnerability in the latest version, please email me directly at hank@henrygd.me, or [submit a private advisory](https://github.com/henrygd/beszel/security/advisories/new).
+
+If you submit an advisory, open an empty issue as well to let me know that you did (or email me), as I'm not sure if I get notifications for that.
+
+If the issue is low severity (use best judgement) you may open an issue for it instead of contacting me directly.

 Assuming the agent is running, the connection is probably being blocked by a firewall. You have two options:
 
-1. Add an inbound rule to the agent system's firewall(s) to allow TCP connections to the port. Check any active firewalls, like iptables, and in your cloud provider account if applicable.

 ### Connecting the hub and agent on the same system using Docker
 
-If using host network mode for the agent but not the hub, you can add your system using the hostname `host.docker.internal`, which resolves to the internal IP address used by the host. See [example docker-compose.yml](/supplemental/docker/same-system/docker-compose.yml).

 ### Docker container charts are empty or missing
 
-If container charts show empty data, or don't show up at all, you may need to enable cgroup memory accounting. To verify, run `docker stats`. If that also shows zero memory usage, follow this guide to fix:
