DescriptionNVD

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.

AnalysisAI

Stored cross-site scripting in the Buzz Comments WordPress plugin (all versions up to 0.9.4) allows authenticated administrators to inject arbitrary JavaScript via the 'Custom Buzz Avatar' setting, with the malicious script executing whenever any user accesses the plugin settings page. The vulnerability requires high-privilege administrative access and manual interaction with the settings interface, limiting its practical exploitability to insider threats or compromised administrator accounts.
