CVE-2023-5204Public exploitNetwork attack vector

Database disclosure via unprepared search-response query

Published Oct 19, 2023 · Updated Apr 8, 2026

SQL injection in QuantumCloud WPBot 4.8.9 and earlier allows remote attackers to extract database data through an AJAX request. qc_wpbo_search_response passes the POST strid value, sanitized only with sanitize_text_field, into an unprepared wpdb get_results query. The nopriv AJAX hook exposes the function without authentication, and time-based blind queries can disclose sensitive records, including password hashes.
