Vulnerability Overview

The Simple Buttons Creator plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the "Add Button" functionality in all versions up to, and including, 1.04 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. NOTE: This issue is exploitable as an unauthenticated user, as well as via Cross-Site Request Forgery, due to a lack of authorization and nonce checks, respectively, within the affected function.

Technical Analysis
