## Description

The Pinterest for WooCommerce plugin for WordPress is vulnerable to Stored Cross-Site Scripting in versions 1.2.5 up to, and including, 1.5.1 due to the settings REST endpoint saving every submitted key, including server-owned Pinterest account data, and the catalog page rendering the stored ad credits value as HTML without sanitization. This makes it possible for authenticated attackers with shop manager-level access and above to inject arbitrary web scripts that execute whenever an administrator accesses the plugin's catalog page.
