How to fix or mitigate EUVD-2026-93072?

Within 24 hours, inventory every WordPress installation using Groundhogg and confirm whether versions 4.8.3 or earlier are present; where Groundhogg is not business-critical, deactivate and remove the plugin immediately, and where it must remain operational, place the affected sites behind a web application firewall or reverse proxy with rules blocking unauthorized access to the plugin's endpoints and increase logging and monitoring on those paths. Within 7 days, engage the vendor for a timeline on a fixed release and, if the plugin must stay live, isolate the affected sites from sensitive data stores, rotate any credentials, API keys, or tokens that the plugin has access to, and confirm that no confidential data has been retrieved by reviewing access logs for anomalous requests. Within 30 days, upgrade to a patched Groundhogg release as soon as the vendor publishes one, and if none is available, replace Groundhogg with a maintained alternative or formally accept the risk with documented compensating controls, while verifying that all remaining installations are either updated or decommissioned.
