Tigroumeow · Media Cleaner: Clean Your Wordpress! · CVE-2026-4912
**Name of the Vulnerable Software and Affected Versions**
Media Cleaner: Clean your WordPress! versions prior to 7.0.4
**Description**
An issue exists where the `get urls from html()` function uses `DOMDocument::loadHTMLFile()` to fetch iframe source URLs. The process employs an insufficient hostname validation check based on a substring match against the site server name. This allows authenticated attackers with Administrator-level access or higher to perform Server-Side Request Forgery (SSRF), enabling them to initiate web requests to arbitrary locations from the application to query or interact with internal services.
**Recommendations**
Update to version 7.0.4 or later.
As a temporary mitigation, restrict access to the `get urls from html()` function.
