Vulnerability from github – Published: 2026-07-28 21:31 – Updated: 2026-07-28 21:31
VLAI
Details
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.
