Infility Global <= 2.15.21 - Unauthenticated Stored Cross-Site Scripting via /cf7_record Log Endpoint

The Infility Global plugin for WordPress is vulnerable to Stored Cross-Site Scripting via /cf7_record Log Endpoint in all versions up to, and including, 2.15.21 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. The /cf7_records viewer is accessible to any authenticated user including those with Subscriber-level access, meaning the injected payload executes for any logged-in user who visits the records page.
