Researcher Grzegorz Niedziela


The MonsterInsights plugin for WordPress is vulnerable to Stored Cross-Site Scripting via post titles and pages in versions up to, and including, 8.9.0 due to insufficient input sanitization and output escaping on those values. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page if they are able to successfully spoof a request to Google Analytics.
