Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in Themepoints Accordion plugin <= 2.6 versions.

The Accordion plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's 'tcpaccordion' shortcode in all versions up to, and including, 2.6 due to insufficient input sanitization and output escaping on user supplied attributes. This makes it possible for authenticated attackers with contributor-level and above permissions to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

The tab GET parameter of the settings page is not sanitised or escaped when being output back in an HTML attribute, leading to a reflected XSS issue.

An issue was discovered in the Accordion plugin before 2.2.9 for WordPress. The unprotected AJAX wp_ajax_accordions_ajax_import_json action allowed any authenticated user with Subscriber or higher permissions the ability to import a new accordion and inject malicious JavaScript as part of the accordion.
