The Automotive Car Dealership Business WordPress Theme for WordPress is vulnerable to Stored Cross-Site Scripting via the 'Project Details' custom field in Portfolio Items in all versions up to, and including, 13.4.1. This is due to insufficient input sanitization and output escaping on user-supplied attributes in the 'project_details' custom field. This makes it possible for authenticated attackers, with contributor-level permissions and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
