Advanced Database Cleaner < 3.1.7 - Settings Manipulation via CSRF

Description

The plugin is vulnerable to Cross-Site Request Forgery due to missing or incorrect nonce validation on the aDBc_prepare_elements_to_clean() function. This makes it possible for unauthenticated attackers to alter the keep last setting via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
