This makes it possible for authenticated attackers, with subscriber-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This requires the Free Listing Submission feature to be enabled, which is shipped on by default via the Setup Wizard demo configuration.","summary":"The Motors car dealership plugin for WordPress does not sanitize the 'stm_f_s[make]' parameter, so a logged-in subscriber can store a script on a page.
