Authenticated database disclosure via unescaped advance filter
Published Aug 5, 2026 · Updated Aug 5, 2026
SQL injection in weDevs WP ERP 1.17.4 and earlier allows remote authenticated users to read database data via erpadvancefilter. The AJAX handler applies sanitize_text_field, which preserves single quotes, before erp_crm_contact_advance_filter() inserts the value into a single-quoted SQL WHERE clause executed by $wpdb->get_results(). Exploitation requires erp_crm_list_contact, granted to the plugin CRM Agent role and higher roles, and exposes sensitive database information without changing data.
