Description
Cacti's sanitize_sql_column (lib/functions.php) sanitizes user-supplied ORDER BY column names using the regex . Because this allowlist retains letters, digits, underscore, parentheses, and dot (intended to support expressions like COUNT(id) and table.column), a payload such as passes through completely unmodified.
