Vvveb through 1.0.8.6 contains an SQL injection vulnerability because the @KEYS(:each) macro emits PHP array keys as backtick-quoted INSERT column names without escaping, and several procedures in admin/sql/mysqli/product.sql and admin_auth_token.sql omit the @FILTER guard. Authenticated back-office users able to save products can submit product_<feature> POST array keys containing backticks to redirect bound values into unexposed columns or break SQL statements.
