Description

The Watu Quiz plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's 'watu-basic-chart' shortcode in all versions up to, and including, 3.4.1 due to insufficient input sanitization and output escaping on user supplied attributes. This makes it possible for authenticated attackers with contributor-level and above permissions to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

Affected products

• Bob Watu Quiz: before 3.4.1.1 — fixed in 3.4.1.1

How to fix

Upgrade to a fixed version: Bob Watu Quiz 3.4.1.1. Check the vendor advisory for mitigations.
