The Welcart e-Commerce plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'ordermail' setting in versions up to, and including, 2.11.22. This is due to insufficient sanitization on the ordermail field and a lack of escaping on output. This makes it possible for authenticated attackers, with Editor-level permissions and above, to inject arbitrary web scripts via the General Setting page that will execute when an administrator accesses the E-mail Setting page.
The Welcart e-Commerce plugin for WordPress is vulnerable to Stored Cross-Site Scripting via settings in all versions up to, and including, 2.11.20 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with editor-level permissions and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This only affects multi-site installations and installations where unfilteredhtml has been disabled.
The Welcart e-Commerce plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the ‘name’ parameter in all versions up to, and including, 2.11.9 due to insufficient input sanitization and output escaping.

The Welcart e-Commerce plugin for WordPress is vulnerable to unauthorized access of data due to a missing capability check on the 'uscesexport' action in all versions up to, and including, 2.11.24.

PayPal api secret) , as well as business contact details, mail templates, and other operational settings tied to the store.
