Go to dashboardThe Opti-Behavior WordPress plugin up to and including 1.9.2.1 fails to sanitize the country_name location parameter sent to its heatmap recording endpoint. An unauthenticated attacker can store a script that runs in the browser of anyone who loads the injected page.
Summary written from the sources below. Check the originals before acting.

Sites running the Opti-Behavior WordPress plugin at version 1.9.2.1 or earlier are exposed, because the recording endpoint accepts requests from any visitor who can fetch a nonce. Sites that do not have the plugin installed are not affected. The sources do not say whether non-default settings change exposure.

The Opti-Behavior – Self-Hosted Heatmaps, Session Recordings, Funnels, A/B Testing & Smart Insights plugin for WordPress is vulnerable to Stored DOM-Based Cross-Site Scripting via 'country_name' Location Parameter in all versions up to, and including, 1.9.2.1 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 heatmap recording endpoint accepts unauthenticated requests protected only by a nonce that any visitor can freely obtain via the public opti_behavior_refresh_nonces AJAX action, removing any practical barrier to injecting the malicious payload.
