The Counter Box: Add Engaging Countdowns, Timers & Counters to Your WordPress Site plugin for WordPress is vulnerable to DOM-Based Stored Cross-Site Scripting via the ‘content’ parameter in all versions up to, and including, 2.0.6 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with administrator-level access, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
