accordion

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.

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.
