Accordion < 2.7 - Authenticated (Editor+) Stored Cross-Site Scripting via accordion settings

Description

The Accordion plugin for WordPress is vulnerable to Stored Cross-Site Scripting via several parameters in versions up to, and including, 2.6 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with editor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
