As immediate action, update the affected plugin. If you're unable to do so, ask your hosting provider or web developer for help.

Note by Patchstack

The vendor has implemented measures to notify users about potential API misuse when the API key is not restricted to requests from defined domain names or IP addresses. The exposure of the API key is now considered logic by design. Users are informed about the associated risks, and additional safeguards will be introduced on the API key creation and management page.
