## Description

The Copy Anything to Clipboard plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the [copy] / [ctc] shortcode's 'success-text', 'copied-text' and 'button-text' attributes (and the [copy_inline] shortcode's 'tooltip' attribute) in all versions up to, and including, 5.5.4, due to insufficient input sanitization of HTML-entity-encoded markup and the front-end script writing these values into the page with innerHTML. 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 clicks the copy button on an injected page.
