CVE-2026-6041

MEDIUM

Buzz Comments <= 0.9.4 - Authenticated (Administrator+) Stored Cross-Site Scripting via 'Custom Buzz Avatar' Setting

Title source: cna
STIX 2.1

Description

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.
