- Mitigation guidance
- To mitigate this issue, disable DNS-over-HTTPS (DoH) support in Unbound if it is not required. This can typically be achieved by commenting out or removing the `do-https:` configuration block in the `unbound.conf` file and restarting the Unbound service. Disabling DoH may affect clients relying on this protocol for DNS resolution. A service restart is required for the changes to take effect.
