CVE-2026-11801Network attack vector

Information disclosure via unprotected classifieds-types endpoint

Published Aug 18, 2026 · Updated Aug 18, 2026

Authorization bypass in WPAdverts before 2.3.3 allows remote attackers to read internal site configuration via the classifieds-types REST endpoint. The affected REST handler in class-rest-blocks.php returns registered post types, taxonomy labels, form scheme metadata, contact options, and custom field meta keys without an effective authorization check on vulnerable releases. No account or user interaction is required; published records describe configuration disclosure only and do not report data modification or service interruption.
