SQL injection vulnerability in the "the_search_function" function in cardoza_ajax_search.php in the AJAX Post Search (cardoza-ajax-search) plugin before 1.3 for WordPress allows remote attackers to execute arbitrary SQL commands via the srch_txt parameter in a "the_search_text" action to wp-admin/admin-ajax.php.
Improper Neutralization of Special Elements used in an SQL Command The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. Without sufficient removal or quoting of SQL syntax in user-controllable inputs, the generated SQL query can cause those inputs to be interpreted as SQL instead of ordinary user data.
