"value": "The WP Optimizer plugin for WordPress is vulnerable to SQL Injection via the 's' parameter in all versions up to and including 2.5.0. This is due to an unsafe subquery-detection branch in the Query::parse_key_compare_field() method that, when the user-supplied value matches the regex ^[(\\s]*SELECT\\s+, wraps the value in parentheses and embeds it directly into the SQL string without any escaping or quoting. While the normal LIKE code path correctly uses esc_sql($wpdb->esc_like(...)) and wraps the value in single quotes, this branch completely bypasses those protections. Because the attack payload (SELECT ...) contains no single quotes, WordPress's wp_magic_quotes() provides no protection. This makes it possible for authenticated attackers with administrator-level access to inject arbitrary SQL subqueries — including time-based blind payloads — that can be used to extract sensitive information from the database."
