 "title": "QA Assistants – Driven by data <= 5.3.0.1 - Unauthenticated Stored Cross-Site Scripting via 'event_ary' Parameter",
 "description": "The QA Assistants – Driven by data plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'event_ary' parameter of the public behavioral tracking endpoint in all versions up to, and including, 5.3.0.1, due to insufficient input validation of submitted event rows and insufficient output escaping when the recorded event data is embedded in a single-quoted JavaScript string on the session replay screen. This makes it possible for unauthenticated attackers to inject arbitrary web scripts that will execute whenever an administrator or another user with analytics access views the replay of the affected session.",
