Perfmatters < 2.2.0 - Authenticated (Subscriber+) Stored Cross-Site Scripting

Description

The Perfmatters plugin for WordPress is vulnerable to Stored Cross-Site Scripting via an unknown parameter in all versions up to 2.2.0 (exclusive) due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with subscriber access or above to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
