Description

The Betheme theme for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's Button shortcode and Custom CSS field in all versions up to, and including, 28.0.3 due to insufficient input sanitization and output escaping on user supplied attributes. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

Affected products

• MuffinGroup Betheme: before 28.0.4 — fixed in 28.0.4

How to fix

Upgrade to a fixed version: MuffinGroup Betheme 28.0.4. Check the vendor advisory for mitigations.
