Description

The Vantage theme for WordPress is vulnerable to Stored Cross-Site Scripting via Gallery block text content in versions up to, and including, 1.20.32 due to insufficient output escaping in the gallery template. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
