Authenticated data disclosure via unchecked AJAX action
Published Aug 8, 2026 · Updated Aug 8, 2026
Information disclosure in WP Directory Kit before 1.5.5 allows remote authenticated users to read user and unpublished listing data. The wdk_admin_action AJAX handler accepts function=index requests without an authorization or nonce check and returns the Listings Management grid. Subscriber-level access and another user's draft or unapproved listing are required; exposure includes account IDs, display names, and hidden titles.
