AnalysisAIv1 – Jul 28, 2026

Server-Side Request Forgery (SSRF) in the Media Cleaner WordPress plugin through version 7.0.3 allows authenticated administrators to make arbitrary web requests from the server, potentially probing internal services. The flaw stems from insufficient hostname validation in the get_urls_from_html() function, enabling bypass via substring matching. No active exploitation or public proof-of-concept is identified, and the high privilege requirement limits the attack surface.

DescriptionCVE.org

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.
