Slimstat Analytics < 4.9.3 is vulnerable to Unauthenticated Stored XSS vulnerability

The Slimstat Analytics plugin for WordPress is vulnerable to Stored Cross-Site Scripting via REQUEST_URI in versions up to, and including, 4.9.2 due to insufficient input sanitization and output escaping when logging visitor requests. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever an administratoruser views those logs.
