CVE-2026-11801

gwin WPAdverts – Classifieds Plugin

The WPAdverts – Classifieds Plugin plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 2.3.2. This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for unauthenticated attackers to retrieve internal site configuration data exposed by the classifieds-types REST endpoint, including registered post types, labels, associated taxonomies, form scheme metadata, contact options, and custom field meta keys.
