Description
The WPBookit plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'css_code' parameter in all versions up to, and including, 1.0.6 due to a missing capability check on the save_custome_code() function. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
