Descriptions

The Sloth Logo Customizer WordPress plugin through 2.0.2 does not have CSRF check when updating its settings, and is missing sanitisation as well as escaping, which could allow attackers to make logged in admin add Stored XSS payloads via a CSRF attack

The Sloth Logo Customizer plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 2.0.2. This is due to missing or incorrect nonce validation on the setting() function. This makes it possible for unauthenticated attackers to update the plugin's settings and inject malicious JavaScript via a forged request, granted they can trick a site administrator into performing an action such as clicking on a link.
