Until an official fix is available, restrict Administrator-level access to trusted users only and monitor for suspicious activity related to the plugin. Avoid exposing sensitive internal services that could be targeted via SSRF. Follow vendor updates closely for an official patch or mitigation.
Description
The Media Cleaner: Clean your WordPress! plugin for WordPress is vulnerable to Server-Side Request Forgery in all versions up to, and including, 7.0.3. This is due to the `get_urls_from_html()` function using `DOMDocument::loadHTMLFile()` to fetch iframe source URLs with an insufficient hostname validation check that relies on a substring match against the site's server name. This makes it possible for authenticated attackers, with Administrator-level access and above, to make web requests to arbitrary locations originating from the web application, which can be used to query and interact with internal services.
