CWE: CWE-89 \u2014 Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')
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.

Code:
    protected void doSDODistance(
            BinarySpatialOperator filter, Expression e1, Expression e2, Object extraData)
            throws IOException {
        double distance = ((DistanceBufferOperator) filter).getDistance();
        String unit = getSDOUnitFromOGCUnit(((DistanceBufferOperator) filter).getDistanceUnits());

        String within = filter instanceof DWithin ? "TRUE" : "FALSE";

        out.write("SDO_WITHIN_DISTANCE(");
        e1.accept(this, extraData);
        out.write(",");
        e2.accept(this, extraData);

        // encode the unit verbatim when available
        if (unit != null && !"".equals(unit.trim())) {
            unit = escapeLiteral(unit);
            out.write(",'distance=" + distance + " unit=" + unit + "') = '" + within + "' ");
        } else out.write(",'distance=" + distance + "') = '" + within + "' ");
    }
