CVE-2026-8939

The Search Simple Fields plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 0.2. This is due to missing or incorrect nonce validation on the search_simple_fields_options() function in functions_admin.php. This makes it possible for unauthenticated attackers to modify the plugin's settings — including post types to search in, custom fields, media fields and the custom media function name — via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
