 "title": "MxChat <= 3.2.25 - Unauthenticated Stored Cross-Site Scripting via Rating Feedback",
 "description": "The MxChat plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the public chat rating feedback in all versions up to, and including, 3.2.25. This is due to insufficient output escaping: visitor feedback was placed into an HTML title attribute on the Transcripts screen without escaping quotes. The rating handler also accepted feedback for any session ID and let existing feedback be overwritten. This makes it possible for unauthenticated attackers to inject arbitrary web scripts that execute whenever an administrator views the chat transcripts.",
