Contributor-level revenue disclosure via unchecked AJAX handler
Published Aug 3, 2026 · Updated Aug 3, 2026
Missing authorization in RadiusTheme Classified Listing before 5.4.4 allows remote authenticated users to read daily store revenue totals. The rtcl_revenue_order_search AJAX handler validates a nonce but omits a capability check before returning aggregated revenue for an attacker-chosen date range. A Contributor account, an editor-exposed nonce, and at least one completed built-in payment are required; disclosure is limited to daily totals.
