Medium (4.4). EPSS 0.2% chance of exploitation in the next 30 days.
The Buzz Comments plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'Custom Buzz Avatar' (buzz_comments_avatar_image) setting in all versions up to, and including, 0.9.4. This is due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with Administrator-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses the plugin settings page.
