Strapi is an open-source content management system. Prior to version 4.25.2, inputting a local domain into the Webhooks URL field leads to the application fetching itself, resulting in a server side request forgery (SSRF). This issue has been patched in version 4.25.2.
The web server receives a URL or similar request from an upstream component and retrieves the contents of this URL, but it does not sufficiently ensure that the request is being sent to the expected destination.
