Summary
The ProfileGrid plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'pm_author_message' parameter in the pm_send_message_to_author function in all versions up to 5.9.9.2 due to insufficient input sanitization and output escaping.
Risk Assessment
Authenticated attackers with Subscriber-level access or higher can inject arbitrary web scripts that execute when users visit affected pages, potentially leading to session theft, redirects, or other malicious actions.
Recommendation
Immediately update the ProfileGrid plugin to the latest available version that includes a complete fix. Version 5.9.8.5 only provides a partial patch, so a full update is required.
