What the vulnerability does
01Description
The Tour & Activity Operator Plugin for TourCMS plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'target' parameter of the tourcms_doc_link shortcode in all versions up to, and including, 1.7.0 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with Contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
