Description
The Brizy plugin for WordPress is vulnerable to Stored Cross-Site Scripting via SVG file uploads in all versions up to, and including, 2.8.23 due to the SVG sanitizer only being applied when the client-supplied MIME type equals image/svg+xml, while WordPress stores and serves the file based on its extension. This makes it possible for authenticated attackers, with author-level access and above, to upload a .svg file declared with a different MIME type, bypassing sanitization and injecting arbitrary web scripts that will execute whenever a user accesses the uploaded file.
