Description

The Async Javascript plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the '&aj_gtmetrix_username=' and '&aj_gtmetrix_api_key=' parameters in versions up to, and including, 2.20.12.09 due to insufficient input sanitization and output escaping. This makes it possible for authenticated (admin+) attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
