## Overview

The Gutenberg Blocks – PublishPress Blocks plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'Marker Title' and 'Marker Description' parameters for the Maps block in versions up to, and including, 3.3.4 due to insufficient input sanitization and output escaping. 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.

## Remediation
