Vulnerability Description
The Chatbot for WordPress by Collect.chat plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the '_inpost_head_script[synth_header_script]' post meta field in all versions up to, and including, 2.4.8 due to insufficient input sanitization and output escaping.
