SVG Support < 2.5.11 - Author+ Stored XSS via SVG File Upload

Description

The plugin is vulnerable to Stored Cross-Site Scripting via SVG File uploads due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with Author-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses the SVG file. By default, this can only be exploited by administrators, but the ability to upload SVG files can be extended to authors.
