Asset CleanUp: Page Speed Booster < 1.4.0.6 - Unauthenticated Stored XSS via Comment Content

Description

The plugin is vulnerable to Stored Cross-Site Scripting via Comment Content due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This is only exploitable on instances where combine_loaded_css has been enabled.
