Official description

The Demo Importer Plus plugin for WordPress is vulnerable to XML External Entity Injection (XXE) in all versions up to, and including, 2.0.9 via the SVG file upload functionality. This makes it possible for authenticated attackers, with Author-level access and above, to achieve code execution in vulnerable configurations. This only impacts sites on versions of PHP older than 8.0.

The underlying weakness: Improper Restriction of XML External Entity Reference

The product processes an XML document that can contain XML entities with URIs that resolve to documents outside of the intended sphere of control, causing the product to embed incorrect documents into its output.

How developers prevent this class of flaw

  • Many XML parsers and validators can be configured to disable external entity expansion.
