Vulnerability Overview

The Enable SVG, WebP & ICO Upload plugin for WordPress is vulnerable to Stored Cross-Site Scripting in versions up to, and including, 1.1.1 due to insufficient sanitization of SVG uploads. This makes it possible for authenticated attackers, with author-level permissions and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
