Recommendation: Monitor — no exploitation signal at the moment.

The Crisp Live Chat WordPress plugin is vulnerable to Cross-Site Request Forgery due to missing nonce validation via the crisp_plugin_settings_page function found in the ~/crisp.php file, which made it possible for attackers to inject arbitrary web scripts in versions up to, and including 0.31.
