The Blocksy Companion plugin for WordPress is vulnerable to Stored Cross-Site Scripting via SVG uploads in versions up to, and including, 2.0.45 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with contributor-level permissions and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
