What the vulnerability does
01Description
The Simple Folio plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the '_simple_folio_item_client_name' and '_simple_folio_item_link' meta fields in all versions up to, and including, 1.1.1 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.
