Description

The WP Live Chat Support for WordPress is vulnerable to Stored Cross-Site Scripting via the quick response and post functions in versions up to, and including, 8.1.9 due to insufficient input sanitization and output escaping. This makes it possible for subscriber-level attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
