DescriptionCVE.org

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.

AnalysisAI

Unauthenticated access to the classifieds-types REST endpoint in WPAdverts - Classifieds Plugin for WordPress (all versions through 2.3.2) exposes internal site configuration data due to a missing authorization check in class-rest-blocks.php. Remote attackers without any credentials can retrieve registered post types, taxonomy definitions, form schema metadata, contact options, and custom field meta keys - information that supports targeted reconnaissance for follow-on attacks. …
